Exploration of anti-cardiac fibrosis active ingredients of Eucalyptus globulus Labill. fruit and their mechanism of action based on chromatography-mass spectrometry and network pharmacology Minjie Li, Xiaoli Wang, Tianyu Cheng, Weizhuo Tang, Xiaoshu Zhang 2023 (1):  1-14.  摘要 ( 752 )   PDF(3953KB) ( 344 )   Abstract The fruit of Eucalyptus globulus Labill., also known as “Yikouzhong (YKZ)” in China, belongs to the myrtaceae family. The aim of this study was to characterize the chemical composition of YKZ extract by GC-MS combined with LC-MS/MS. A total of 34 compounds were initially identified by GC-MS and 54 compounds were identified by LC-MS/MS positive and negative total ion flow maps. The total phenols and flavonoid-like substances were quantified using an enzyme standardization method to determine the presence of phenolic substances in them. At the same time, a network pharmacology approach based on LC-MS/MS was used to construct a “drug-component-target” network for myocardial protection, and 696 potential anti-myocardial fibrosis targets were obtained. The PPI analysis identifi ed 72 core targets, and the enrichment analysis revealed that the core targets may exert anti-myocardial fibrosis effects by regulating Lipid and atherosclerosis and Proteoglycans signaling pathways. Taken together, these results suggest that YKZ anti-cardiac fibrosis may act through multiple components and targets, and this study provides a scientific basis for the functional development and application of YKZ against myocardial fibrosis. 相关文章 | 计量指标

Application and action mechanism of polyphenol delivery system Jia Kang, Junguo Wang, Junan Zheng, Changqing Xie, Jiaqing Cao, Xiangrong Zhang 2023 (1):  15-25.  摘要 ( 742 )   PDF(2527KB) ( 183 )   Abstract Polyphenols are a class of chemical components that are benefcial to human health. Polyphenol compounds provide advanced biomedical applications due to their antioxidant and anti-infammatory activity. They can also play a role in reducing the risk of various chronic diseases. However, most polyphenols are unstable compounds with low absorption and poor bioavailability which greatly limited their applications. Therefore, the delivery of polyphenols to specifc parts of the body has become a therapeutic necessity. In this study, the research of polyphenol delivery systems such as microspheres, nanoparticles, liposomes and gels were mainly summarized. The action mechanism of polyphenols to intestinal microbiota, tumor cells, the brain, pancreas, and liver was analyzed. 相关文章 | 计量指标

The mechanism of polyphenols in perilla against hyperuricemia using network pharmacology and molecular docking Lingling Wang, Aijinxiu Ma, Xu Zhao 2023 (1):  26-34.  摘要 ( 657 )   PDF(3154KB) ( 210 )   Abstract To investigate the possible targets and mechanisms of polyphenols in perilla in the treatment of hyperuricemia (HUA) Batman-TCM, TCMSP, PubMed, and CNKI databases were used to obtain the main components of perilla and component- related targets. HUAtargets were collected through GeneCards and OMIM online platforms. The HUAtarget and the perilla component target were crossed to obtain a common target. Protein interaction networks were constructed using the STRING database, and the compound-target-pathway network was constructed by Cytoscape software. The GO and KEGG enrichment analysis was performed using the DAVID database. Molecular docking was used to verify the results. Thirteen potential active components, 101 component targets, 901 HUA-related targets, and 36 common targets were screened out. Through network topology analysis, core targets such as TP53, TNF, CASP3, and PPARG and active components such as luteolin, β-carotene, cyanidin, catechin, and linolenic acid ethyl ester were obtained. The topology analysis of the “compound-target- pathway” network showed that the polyphenolic compounds luteolin, cyanidin, and catechin were the main active components of the perilla in the treatment of HUA. This study showed that the treatment of HUA with perilla had the characteristics of a multi-component, multi-target, and multi-signal pathway, which provided a scientifc basis for further study on the molecular mechanism of the treatment of HUAwith the potential active components of perilla. 相关文章 | 计量指标

Polyphenols extracted from Aronia melanocarpa by combined enzymatic and ultrasonication and their antioxidant potential and antimicrobial activity Xinzhu Zhang, Ming Song, Weizhuo Xu, Wei Xu 2023 (1):  35-47.  摘要 ( 546 )   PDF(999KB) ( 82 )   Abstract The extraction of polyphenols from Aronia melanocarpa was carried out using a combination of enzymatic and ultrasound. After single-factor and orthogonal design and experiment, the optimized polyphenol extraction conditions were 1% enzyme, 1:40 material-to-liquid ratio, 55 ℃, 60 min ultrasonication, 70% ethanol, and the fi nal extraction amount was 88.634 mg/g, which displayed a 25.15% and 34.08% improvement compared with the single ultrasonication and enzymatic extraction methods, respectively. Significant antibacterial effects of polyphenols were shown against Staphylococcus aureus, Escherichia coli and Bacillus subtilis. Further antioxidation eff ects were evaluated, and the superoxide anion radical scavenging rate, hydroxyl radical scavenging rate and DPPH free radical scavenging rate reached 45.2%, 83.5% and 85.4%, respectively. This combined enzymatic and ultrasonic extraction method exhibited the advantages of high extraction rate, saving solvent consumption and extraction time, but also provided a new method for the development and utilization of natural antimicrobial and antioxidant health products. 相关文章 | 计量指标
