    Abstract:
    Objective: A typical case of Xianling Gubao (XLGB) Tablets-induced liver injury was systematically studied in the clinic and the laboratory. Methods: A patient with herb-induced liver injury (HILI) and a history of taking XLGB Tablets before disease onset was engaged as the study subject, and the case was diagnosed according to the updated Roussel Uclaf Causality Assessment Method (RUCAM) and the integrated evidence chain (iEC) method recommended by the Guidelines for Diagnosis and Treatment of Herb-induced Liver Injury (HILI Guidelines). Results: Clinical history, biochemical indexes and imaging tests were used to exclude the influence of fundamental diseases and confusing liver diseases such as viral, alcoholic and autoimmune liver diseases on the diagnosis. Based on an investigation of the patient’s medication history, she was suspected to have HILI caused by XLGB Tablets, as the patient was only taking an oral preparation of XLGB Tablets, and the influence of other drugs on the diagnosis was excluded. This patient with alanine aminotransferase (ALT)≥ 3× upper limit of normal (ULN) and a calculated R of 6 was diagnosed with possible acute drug-induced hepatocellular injury. The relationship was considered ‘‘highly probable” (score of 9) using the updated RUCAM of 2016. Moreover, the fingerprint similarity between the preparation taken by the patient and a commercially available preparation was 0.99, suggesting that the patient was consuming XLGB Tablets rather than another drug. LC-MS technology and the Agilent Fake TCM-Drugs database were used to investigate the drug, and no chemical additions were found. Examination of the drug for pesticide residues, heavy metals, aflatoxins and other exogenous substances indicated compliance with the content limits of the Chinese Pharmacopoeia. Conclusion: In summary, the final diagnosis of XLGB-induced liver injury reached the clinical diagnosis of HILI and was acute severe hepatocellular injury type by the updated RUCAM and iEC. Therefore, this study provides scientific evidence regarding the causality evaluation of compound preparations of traditional Chinese medicines-induced liver injury.
    Abstract:
    Raspberries are used for both food and medicine, but it has not yet attracted widespread attention. In this paper, the chemical constituen of the original plant raspberry. R. chingii is one of the new "Zhe Bawei" medicinal materials selected in 2017. ‘‘Zhe Bawei” refers to eight kinds of genuine medicinal materials in Zhejiang Province. The chemical constituents, pharmacological effects, processing, and application of Rubus chingii Hu were reviewed to provide a reference for its further development. Relevant literature in recent years was collected in databases such as China Knowledge Network, Web of Science, Elsevier, PubMed, and X-Mol, using ‘‘raspberry”, ‘‘Rubus chingii”, ‘‘traditional use”, ‘‘chemical composition”, ‘‘pharmacology”, etc. as keywords individually or in combination. The summary of pharmacological activities shows that the relationship between the pharmacological activities of raspberry is still not deep enough. More in-depth research should be carried out in this direction to explore the mechanism of action of its active ingredients and provide effective reference for the further development of the raspberry industry. In the future, with the participation of more researchers, it is expected to develop innovative drugs based on raspberry for the treatment of diseases.

    Abstract:
    In Northeast China, Goubao pickle is a popular food fermented from the roots of Platycodon grandiflorum as the main material, offering a unique flavor and rich nutritional value. Platycosides in roots of P. grandiflorum may play a crucial role in determining the quality of Goubao pickle through microorganism fermentation. However, biotransfermation of platycosides has not been reviewed during fermentation. In this study, we reviewed platycosides in chemical diversity, metabolic processes in vivo, biotransformation of platycosides in vitro, and pharmacological effects. Finally, we also discussed how to improve the bioactive secondary platycosides we desire by regulating enzymes from microorganisms in the future.
    Abstract:
    Objective: Goji (fruits of Lycium spp.) is commonly consumed as food and medicine. The increasing market demand for goji has led to its wide cultivation and broad breeding, which might cause loss of genetic diversity. This study aims to uncover the genetic diversity of the cultivated and wild Lycium. Methods: The chloroplast genome (CPG) of 34 accessions of Chinese food-medicinal Lycium spp., including the popular cultivars and their wild relatives, was re-sequenced and assembled, based on which the genetic diversity was evaluated. Results: Sequence structural comparison shows that CPG is comparatively conserved within species. Phylogenetic analysis indicates that CPG is sufficient for the discrimination of Lycium species; combined with nuclear ribosomal internal transcribed spacer (Nr ITS) sequences, materials with mixed genetic backgrounds can be identified. Nucleotide diversity analysis reveals that the modern cultivars are probably with a common maternal parent, while the wild accessions are with higher level of genetic diversity. Conclusion: For the first time this study reveals the intraspecies genetic diversity of Lycium spp. using CPG, highlighting the urgent conservation demand of wild genetic resources of Lycium. Our study also demonstrates that CPG provides crucial evidence for identification of Lycium species with mixed genetic backgrounds and highlights the importance of the wild relatives in genetic diversity conservation. This CPG-based technology will contribute to the sustainable development of medicinal plants broadly.
    Abstract:
    Objective: The concept of substances of medicine food homology (SMFH) has garnered significant attention in recent years. This study conducts a systematic analysis of patent literature related to SMFH, and elucidates the development trends, technical hotspots, and the overall patent protection landscape of SMFH in China over the past two decades. Methods: The patent search focused on the SMFH varieties as the objects of inquiry, with retrieval conducted in patent databases. Subsequently, the acquired data underwent processing, analysis, and visualization. Results: While the technical threshold for pharmaceutical applications surpasses that of the food service sector, the former may assume a prominent role in the future. Research and development (R&D) activities in the southeast of China demonstrate robust activity than other regions. Colleges and scientific research institutions exhibit substantial advantages in patent applications compared with individuals and hold greater potential for future development. Conclusion: The findings of this patent analysis indicate that China’s SMFH industry are presently undergoing a transition from an extensive model to a high-quality model. The quality and technical standards of SMFH products are consistently improving. Consequently, there is a need for more stringent patent application requirements to align with the evolving development needs.
    Abstract:
    Objective: Acute lung injury (ALI) is characterized by inflammation and currently lacks an efficacious pharmacological intervention. The medicine combination of Lonicerae Japonicae Flos (LJF) and Forsythiae Fructus (FF) demonstrates combined properties in its anti infective, anti-inflammatory, and therapeutic effects, particularly in alleviating respiratory symptoms. In previous studies, Chinese medicine has shown promising efficacy in lipopolysaccharides (LPS)-induced ALI. However, there have been no reports of LJF and FF pairing for lung injury. The aim of this study is to compare the efficacy of herb pair Lonicerae Japonicae Flos-Forsythiae Fructus (LF) with LJF or FF alone in the treatment of ALI, and to explore whether LJF and FF have a combined effect in the treatment of lung injury, along with the underlying mechanism involved. Methods: A total of 36 mice were divided into six groups (control, model, LJF, FF, LF, dexamethasone) based on the treatments they received after undergoing sham-operation/LPS tracheal instillation. H&E staining and pulmonary edema indexes were used to evaluate lung injury severity. Alveolar exudate cells (AECs) were counted based on cell count in bronchoalveolar lavage fluid (BALF), and neutrophil percentage in BALF was measured using flow cytometry. Myeloperoxidase (MPO) activity in BALF was measured using enzyme-linked immunosorbent assay (ELISA), while the production of IL-1b, TNF-a, and IL-6 in the lung and secretion level of them in BALF were detected by quantitative polymerase chain reaction (qPCR) and ELISA. The effect of LJF, FF, and LF on the expression of caspase-1 and IL-1b proteins in bone marrow derived macrophages (BMDMs) supernatant was assessed using Western blot method under various inflammasome activation conditions. In addition, the concentration of IL-1b and changes in lactatedehydrogenase (LDH) release levels in BMDMs supernatant after LJF, FF, and LF administration, respectively, were measured using ELISA. Furthermore, the effects of LJF, FF and LF on STING and IRF3 phosphorylation in BMDMs were detected by Western blot, and the mRNA changes of IFN-b, TNF-a, IL-6 and CXCL10 in BMDMs were detected by qPCR. Results: LF significantly attenuated the damage to alveolar structures, pulmonary hemorrhage, and infiltration of inflammatory cells induced by LPS. This was evidenced by a decrease in lung index score and wet/dry weight ratio. Treatment with LF significantly reduced the total number of neutrophil infiltration by 75 % as well as MPO activity by 88 %. The efficacy of LF in reducing inflammatory factors IL-1b, TNF-a, and IL-6 in the lungs surpasses that of LJF or FF, approaching the effectiveness of dexamethasone. In BMDMs, the co-administration of 0.2 mg/mL of LJF and FF demonstrated superior inhibitory effects on the expression of nigericin-stimulated caspase-1 and IL-1b, as well as the release levels of LDH, compared to individual treatments. Similarly, the combination of 0.5 mg/mL LJF and FF could better inhibit the phosphorylation levels of STING and IRF3 and the production of IFN-b, TNF-a, IL-6, and CXCL10 in response to ISD stimulation. Conclusion: The combination of LJF and FF increases the therapeutic effect on LPS-induced ALI, which may be mechanistically related to the combined effect inhibition of cyclic-GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) and NOD-like receptor family protein 3 (NLRP3) inflammasomes pathways by LJF and FF. Our study provides new medicine candidates for the clinical treatment of ALI.
    Abstract:
    Objective: Lilium brownii var. viridulum (LB) and L. lancifolium (LL) are the main sources of medicinal lily (Lilii Bulbus, Baihe in Chinese) in China. However, the functional components of these two species responsible for the treatment efficacy are yet not clear. In order to explore the therapeutic material basis of Lilii Bulbus, we selected L. davidii var. willmottiae (LD) only used for food as the control group to analyze the differences between LD and the other two (LB and LL). Methods: Metabolome and transcriptome were carried out to investigate the differences of active components in LD vs LB and LD vs LL. Data of metabolome and transcriptome was analysed using various analysis methods, such as principal component analysis (PCA), hierarchical cluster analysis (HCA), and so on. Differentially expressed genes (DEGs) were enriched through KEGG and GO enrichment analysis. Results: The PCA and HCA of the metabolome indicated the metabolites were clearly separated and varied greatly in LL and LB contrasted with LD. There were 318 significantly differential metabolites (SDMs) in LD vs LB group and 298 SDMs in LD vs LL group. Compared with LD group, the significant upregulation of steroidal saponins and steroidal alkaloids were detected both in LB and LL groups, especially in LB group. The HCA of transcriptome indicated that there was significant difference in LB vs LD group, while the difference between LL and LD varied slightly. Additionally, 47 540 DEGs in LD vs LB group and 18 958 DEGs in LD vs LL group were identified. Notably, CYP450s involving in the biosynthesis of steroidal saponins and steroidal alkaloids were detected, and comparing with LD, CYP724, CYP710A, and CYP734A1 in LB and CYP90B in LL were all up-regulated. Conclusion: This study suggested that steroidal saponins and steroidal alkaloids maybe the representative functional components of Lilii Bulbus, which can provide new insights for Lilii Bulbus used in the research and development of classic famous formula.
    Abstract:
    Objective: Huamaoyan Granules (HMYG) and Huamaoyan Capsules (HMYC) are Chinese patent medicines with different dosage forms of the same prescription. Due to the different preparation process, the chemical composition of these Chinese patent medicines varies greatly among different forms, but there were few studies on the difference comparison and quality control of them. In order to improve the effectiveness and safety in its clinical application, an idea combining high performance liquid chromatography (HPLC) and chemometrics was put forward to study the quality control of Chinese patent medicines in different dosage forms of the same prescription. Methods: The differential markers of HMYG and HMYC were explored based on HPLC fingerprint and chemometrics including orthogonal projections to latent structures-discriminant analysis (OPLS-DA), principal component analysis (PCA), and hierarchical cluster analysis (HCA). Finally, the quantitative analysis method of related components was established by HPLC. Results: A quality control method for HMYG and HMYC was established. Firstly, the chemical components of HMYG and HMYC were systematically analyzed by HPLC fingerprinting. Further exploration showed that there were 20 characteristic peaks and 57 common peaks. Then, the potential differential markers between HMYG and HMYC were explored by chemometrics, and the differential markers were screened after intersection with the 20 characteristic peaks. Finally, HPLC quantitative analysis methods for nine components were established, including seven differential markers (neochlorogenic acid, protocatechualdehyde, chlorogenic acid, cryptochlorogenic acid, caffeic acid, rosmarinic acid and salvianolic acid A). The results of HPLC quantitative analysis showed that the contents of eight components in HMYG and HMYC samples were significantly different. According to the above results, the differential markers between HMYG and HMYC screened based on HPLC fingerprint and chemometrics can effectively characterize the differences between the two dosage forms. Conclusion: The present work provides a rapid and effective method for routine quality evaluation and control of HMYG and HMYC. This work also provides feasible methods for the quality evaluation and control of Chinese patent medicines with different dosage forms of the same prescription.
    Abstract:
    Objective: To investigate the plasma pharmacokinetics of six representative components (nodakenin, osthole, 5-O-methylvisammioside, ferulic acid, liquiritigenin, and liquiritin), which were the ingredients of Qianghuo Shengshi Decoction (QSD) granules, in normal and rheumatoid arthritis (RA) rats administrated QSD granules intragastrically. Methods: A rapid and accurate ultra-high performance liquid chromatography-tandem mass spectrometry (LC-MS/MS) method was developed for the simultaneous determination of six components in plasma, and it showed a good specificity, linearity, intra-day and inter-day precision, intra-day and inter-day accuracy, extraction recovery, stability, and the less matrix effect. Results: The validated LC-MS/MS method was successfully used to compare the plasma pharmacokinetics of six ingredients between normal and RA rats after intragastrical administration of QSD granules and differences in the pharmacokinetics were found in two types of rats. The absorption rate in the RA rats was lower for nodakenin, osthole, 5-O-methylvisammioside, liquiritigenin and liquiritin than in the normal group, while the absorption rate of ferulic acid remained constant in two groups. In comparison with the normal rats, the exposure concentration of nodakenin was higher and that of other five components except for nodakenin was lower under pathological conditions. Additionally, the absorptive amount of nodakenin, osthole, 5-O-methylvisammioside and liquiritin was increased and that of ferulic acid and liquiritigenin was reduced in the RA rats than in the normal rats. Compared with the normal rats, the retention time of nodakenin, ferulic acid and liquiritin was reduced in vivo, whereas the retention time of osthole, 5-O methylvisammioside and liquiritigenin was raised in the body for the RA rats. In contrast to the normal rats, the data demonstrated an increase in the elimination velocity of nodakenin and a decrease in the elimination velocity of the other five components except for nodakenin in the pathological state. Conclusion: This study showed that the pharmacokinetic behavior of the six components, nodakenin, osthole, 5-O-methylvisammioside, ferulic acid, liquiritigenin, and liquiritin, is different in vivo between normal and pathological states of rats, and this research provided the necessary experimental data to explain the pharmacokinetics of QSD granules in both normal and pathological states and provide some references for its clinical application at some level.
    Abstract:
    Objective: Mahuang Guizhi Decoction (MGD), an essential herbal pair in traditional Chinese medicine, is able to release cold, fever and asthma, mainly containing alkaloids, flavonoids, phenylpropanoids and amino acids. However, the absorption and distribution of these four category compounds in vivo still remained unclearly. Methods: In our research, we utilized UPLC-Q-TOF-MS technique to identify the constituents within MGD, as well as the prototypes of MGD and their metabolites absorbed in plasma and brain. We further profiled the drug-time curve of prototypes and metabolites of MGD both in plasma and brain. Results: Our results showed that 105 constituents were characterized in MGD. Thirty of them could be absorbed into blood, and ten of them could be distributed into brain. We also discovered eight new bio-transformed metabolites in blood, and a half of which could pass through the blood–brain barrier. In addition, all components detected in vivo could be absorbed and distributed immediately. Conclusion: These findings provide an approachable method to analyze the potential bio-active compounds in MGD and their in vivo behaviors, which could promote the efficacious material basis study of MGD and the security of clinical utilization.

    Abstract:
    This review is briefly to recall the history of research and development (R&D) of Chinese materia medica (CMM) and to discuss the challenges of Chinese traditional and herbal medicines (CTHM) facing the modern science and technology. The R&D of CTHM is thought to be an important pathway for new drug discovery. Since1949, about 140 approved new drugs have been developed, among which about 80 originated directly or indirectly from medicinal plants. CTHM has gained interest from the international medical, biomedical, and pharmaceutical institutions as a valuable source of potential medicines. For the modernization of CMM and innovative research of CTHM, there are following challenges to be faced: (1) to evaluate the efficacy, pharmacological properties, action mechanism, and active chemical constituents; (2) to develop new methodologies for the quality and safety of CTHM; (3) to apply new “-omics” techniques to accelerate drug discoveries developed from CTHM; and (4) to apply international practices including good agricultural practice, good manufacturing practice, good laboratory practice, and good clinical practice in the R&D of CTHM.

    Abstract:
    Rhubarb is a perennial herb belonging to the genus Rheum L. (Polygonaceae). Rhei Radix et Rhizoma (rhubarb roots and rhizomes) is one of the most popular Chinese materia medica and has been widely used for strong laxative function. About 200 compounds with six different types of skeletons (anthraquinone, anthrone, stilbene, flavonoids, acylglucoside, and pyrone) have so far been isolated from eighteen species of the genus Rheum L. These constituents showed extensive pharmacological activities including cathartic, diuretic, anticancer, hepatoprotective, anti-inflammatory, and analgesic effects, as well as toxicological effects. Chemical fingerprint, LC-MS, and other analytical techniques have been used for the quality control of rhubarb. This comprehensive review summarizes the researches into the isolation, pharmacological activities, and phytochemical analysis reported since investigations began in the late 1940s. In addition, pharmacokinetic studies and clinical application of rhubarb are also discussed in present paper.

    Objective To develop an efficient method to isolate and purify the main components isoaloeresin D and aloin from Aloe vera for its industrial production. Methods High-speed counter-current chromatography was used to isolate isoaloeresin D and aloin in a one-step separation from dried crude extract of A. vera. The biphasic solvent system composed of hexane-ethyl acetate-acetone-water (0.2︰5︰1.5︰5) was used at a flow rate of 1.0 mL/min, while the lipophilic phase was selected as the mobile phase and the apparatus was rotated at 840 r/min. The effluent was detected at 254 nm. Results Isoaloeresin D (53.1 mg) and aloin (106.9 mg) were separated from the crude extract (384.7 mg) with the purities of 98.6% and 99.5%, respectively. Conclusion HSCCC is a powerful technique for isolation and separation of chemical composition from aloe.

    Abstract:
    Objective Ginger (Zingiber officinale) is widely used as a spice in cooking and as a medicinal herb in traditional herbal medicine. The present study was to investigate the analgesic and anti-inflammatory activities of ginger oil in experimental animal models. Methods The analgesic effect of the oils was evaluated by the “acetic acid” and “hot-plate” test models of pain in mice. The anti-inflammatory effect of the oil was investigated in rats, using rat paw edema induced by carrageenan, adjuvant arthritis, and vascular permeability induced by bradykinin, arachidonic acid, and histamine. Indomethacin (1 mg/kg), Aspirin (0.5 g/kg) and Dexamethasone (2.5 mg/kg) were used respectively as reference drugs for comparison. Results The ginger oil (0.25-1.0 g/kg) produced significant analgesic effect against chemically- and thermally-induced nociceptive pain stimuli in mice (P < 0.05, 0.01). And the ginger oil (0.25-1.0 g/kg) also significantly inhibited carrageenan-induced paw edema, adjuvant arthritis, and inflammatory mediators-induced vascular permeability in rats (P < 0.05, 0.001). Conclusion These findings confirm that the ginger oil can be used to treat pain and chronic inflammation such as rheumatic arthritis.

    Abstract:
    Cistanches Herba, a famous traditional Chinese materia medica, has a laudatory title “desert ginseng”. According to Chinese Pharmacopoeia 2000, Cistanches Herba is the dry fleshy stem with scale-like leaves of Cistanche deserticola. In order to expand the drug source, Chinese Pharmacopoeia 2005 increased the plants in Cistanche Hoffmg. et Link (Orobanchaceae), C. tubulosa, and dry scaly leaf succulent stems were as genuine Cistanches Herba and still in use. In order to have more comprehensive understanding on Cistanches Herba, this paper focuses the reviews on the biological characteristics, chemical constituents, and pharmacological activities of Cistanches Herba, and its development prospects are looked forward. It provides the relative theoretical basis for the subsequent research work of Cistanches Herba and can be conducive to the development and utilization of Cistanches Herba.

    Abstract:
    Objective To predict the total flavonoids concentration of Aurantii Fructus fried with bran in its extraction process. Methods Ultraviolet spectrophotometry was used to determine the concentration of total flavonoids in different extraction time (t ) and solvent load (M ). Then the predicted procedure was carried out using the following data: 1) based on Ficks second law, the parameters of the kinetic model could be deduced and the equation was established; 2) Locally weighted regression (LWR) code was developed in the WEKA software environment to predict the concentration. And then we used both methods to predict the concentration of total flavonoids in new experiments. Results After comparing the predicted results with the experimental data, the LWR model had better accuracy and performance in the prediction. Conclusion LWR is applied to analyze the extraction process of Chinese herb for the first time, and it is totally fit for the extraction. LWR-based system is a more simple and accurate way to predict than the established equation. It is a good choice especially for a process which exists no clearly rules, and can be used in the real-time control during the process.

    Abstract:
    Objective The 1-aminocyclopropanecarboxylic acid (ACPC) is a natural micromolecule non-protein amino acid that exists only in plants. Despite the determination of its regulating effects on plants, several bioactivities and effects on animals or humans are still unclear. This review focuses the pharmaceutical effects,above all, the neuroprotective effects of ACPC on the cerebro- and cardiovascular system. Methods Two hundred and seventy nine studies were selected and identified from a total of 2457 references in Medline and Chemical Abstracts from 1957 to 2008. Only 38 articles on neuroprotective effects of ACPC from seven different countries qualified to be included in the analysis. Results ACPC has altogether following six general neuroprotective effects on the brain and nervous system: anti-neurotoxicity induced by NMDA, dynorphin-A, glutamate, and morphine; protection from cerebral neurological injury induced by ischemia; antidepressant and anxiolytic effects; anti-convulsion and -seizures and control of epilepsy; facilitation of spatial learning and memory; and the effect of reducing alcohol consumption. Conclusion ACPC has shown a variety of effects on plants and animals. The bioactivities and pharmaceutical effects on animals are of great significance to medical research and public health. Further clinical trials or epidemiological studies are needed to determine its effect in humans. Food intervention with ACPC-rich vegetables and fruits may be a suitable therapy for cerebro- and cardiovascular system diseases. Administration of trace exogenous ACPC could produce vegetables and fruits of rich endogenous ACPC.

    Abstract:
    Bentysrepinine (Y101), a derivative of repensine, is a novel di-peptide structure isolated from Dichondra repens. In vitro and in vivo tests exhibited that bentysrepinine markedly inhibited DNA-HBV and cccDNA activities. The binding mode of Y101 and repensine with DNA polymerase was driven by hydrophobic interactions. This might provide novel recognition of inhibitory effect of Y101 against HBV, though its inhibition mechanism needs to be validated by bio-assay at cellular level and of polymerase activity. Preliminary docking study suggested that Y101 might be able to inhibit HIV inverse transcriptase, also have the potential to interact with DNA polymerase and HCV NS5B polymerase.

    Abstract:
    Objective A reversed-phase HPLC method was established for the simultaneous determination of five hydrophilic and lipophilic components in the roots of Salvia miltiorrhiza. Methods Hydrophilic components including danshensu, protocatechuic aldehyde, and salvianolic acid B, and lipophilic components such as cryptotanshinone and tanshinone IIA, were successfully separated on a Waters Symmetry C18 reverse- phase column (250 mm × 4.6 mm, 5 μm), with acetonitrile-0.5% phosphoric acid (gradient elution) as mobile phase, the detection wavelength was set at 281 nm with flow rate of 1.0 mL/min, and the column temperature was maintained at 30 °C. Results The recovery of the method was in the range of 95.1%–102.5% and the precision was less than 3% for all five analytes. All the compounds showed good linearity (R2 > 0.9990) in a relatively wide concentration range. Therefore, this HPLC method demonstrated good reproducibility, stability, and accuracy in validation studies. Conclusion Simultaneous quanti?cation of the multiple components by HPLC would be a better strategy for the quality evaluation on the roots of S. miltiorrhiza.
