Jatrorrhizine, an isoquinoline alkaloid, is a bioactive metabolite in common medicinal plants, such as Berberis vernae Schneid., Tinospora sagittata (Oliv.) Gagnep. and Coptis chinensis Franch. These plants have been used for centuries in traditional medicine for their wide-ranging pharmacological properties. This review emphasizes the latest and comprehensive information on the sources, pharmacology, pharmacokinetics and toxicity of jatrorrhizine. Studies on this alkaloid were collected from scientific internet databases, including the Web of Science, PubMed, ScienceDirect, Google Scholar, Elsevier, Springer, Wiley Online Library and Europe PMC and CNKI, using a combination of keywords involving “jatrorrhizine”, “sources”, “pharmacology,” “pharmacokinetics,” and “toxicology”. Jatrorrhizine exhibits anti-diabetic, antimicrobial, antiprotozoal, anticancer, anti-obesity and hypolipidemic properties, along with central nervous system activities and other beneficial activity. Studies of jatrorrhizine have laid the foundation for its application to the treatment of various diseases, but some issues still exist. Further investigations might emphasize 1) specific curative mechanisms of jatrorrhizine and clinical utility, 2) application prospect in the treatment of metabolic disorders, 3) comprehensive investigations of the toxicity mechanisms and 4) interactions of jatrorrhizine with other pharmaceuticals and development of derivatives.
Root rot reduces the yield and medical quality of C. chinensis (Cc). Previous studies of Coptis root rot focused on the identification of pathogens and the rhizosphere microbial community composition. The present study aimed to identify potential pathogenic and antagonistic microorganisms associated with root rot based on a high-throughput sequencing technique to prevent this disease. Healthy and diseased Cc in the endosphere and rhizosphere from the same field were collected to investigate the differences in microbiome composition and function. The results showed that the composition and function of microbes were different. The numbers of animal pathogens, soil saprotrophs, plant saprotrophs, and wood saprotrophs in the endosphere of diseased Cc were higher than those in the healthy endosphere and were dominated by Phaeosphaeriaceae, Cladorrhinum, Fusarium, Exophiala, and Melanommataceae. Fusarium, Volutella, Cladorrhinum, Cylindrocarpon, and Exophiala were significantly enriched in the endosphere of the diseased plants. Co-occurrence network analysis showed that Bacillus was negatively correlated with Fusarium, Volutella, and Cylindrocarpon, indicating that Bacillus may be antagonistic microorganisms. To verify the sequencing results, F. solani and F. avenaceum were isolated and verified as pathogens, and 14 Bacillus strains were isolated, which displayed an apparent suppression effect against the two pathogens on PDA medium and detached roots. The strategy of high-throughput sequencing has the potential for the comprehensive identification of pathogenic and antagonistic microorganisms for plant disease. These results provide research ideas and microbial resources for future studies on mitigating or preventing root rot damage to Cc.

Root rot reduced the yield and medical quality of C. Chinensis. Previous studies of Coptis root rot focused on the identification of pathogens and the rhizosphere microbial community composition. In order to provide more evidence for preventing this disease, the present study was to identify the pathogenic and antagonistic microorganisms based on a high-throughput sequencing technique. The healthy and diseased C. chinensis in the endosphere and rhizosphere from the same field were collected to investigating the differences in microbiome composition and function. The results showed that the composition and function of microbes were different. The animal pathogen, soil saprotroph, plant saprotroph, and wood saprotroph in the endosphere of the diseased C. chinensis were higher than the healthy endosphere, which was dominated by Phaeosphaeriaceae, Cladorrhinum, Fusarium, Exophiala, and Melanommataceae.

Background: Huai-Zhi (HZ), the fresh or dried branches of Sophora japonica (L.) are commonly used to treat several diseases such as heartache, red eyes, and metrorrhagia. The present study aimed to explore the potential mechanisms effects of HZ anti-myocardial ischemia by experiment and integrating network pharmacology. Methods: Isoproterenol was used in this study to establish the myocardial ischemia model in mice. Different extraction processes were used to obtain different HZ extracts with a screening of their anti-myocardial ischemia activities. Furthermore, the network pharmacology methods together with molecular docking were utilized to explore the active components, targets, and mechanism of anti-myocardial ischemia of HZ. Results: The ethyl acetate extract of HZ (HZ-EtOAc) significantly reduced the ST-segment elevation of mice in the preliminary test. The 95% ethanol fraction of the ethyl acetate extract of HZ (HZ-EtOAc-95) significantly reduced the ST-segment elevation, reduced the creatine kinase (CK) activity, reduced the levels of creatine kinase isoenzyme(CK-MB) and cardiac troponin I (cTnI) in serum, increased superoxide dismutase (SOD) activity, and decreased malondialdehyde (MDA) levels in the myocardial tissues. Moreover, these results indicated that HZ-EtOAc extract in mice ameliorates myocardial tissue injury. Additionally, network pharmacology demonstrated that nine active components and 177 protein targets are related to the anti-myocardial ischemic effects of HZ. Its underlying mechanism might be involved in multiple signaling pathways, including mitogen-activated protein kinase, Toll-like receptor, and PI3K-Akt. Conclusion: This study used pharmacological experiments to determine the active site of HZ, and explored its potential mechanism in conjunction with network pharmacology.
