Among these compounds, 8 exhibited the most potent activity at NO production inhibitory assay and DPPH radical scavenging assay, stronger than those of the familiar antioxidative agents, quercetin and resveratrol.
Urinary profiling of cis-diol-containing metabolites in rats with bisphenol A exposure by liquid chromatography-mass spectrometry and isotope labeling.
It was found that high-dose BPA exposure had strong effects on the cis-diol compound metabolism, mostly related to the metabolism of galactose and nucleoside and its analogues.
Antimicrobial activities of Asian ginseng, American ginseng, and notoginseng
This overview interprets the present knowledge of the antimicrobial activities of the three ginseng species and some of their bioactive components against pathogenic bacteria and fungi to facilitate and guide further studies needed to optimize the use of ginsENG and their components to improve microbial food safety and prevent or treat animal and human infections.
HPLC-MS/MS determination of flavonoids in Gleditsiae Spina for its quality assessment.
High-performance liquid chromatography and tandem mass spectrometry combined with chemometric methods were used to allow the fast and accurate identification and quantification of the flavonoids compounds in Gleditsiae Spina, and a classification model was built which showed a high level of accuracy predicting 100% of the samples, correctly.
Quality Evaluation of Mahonia bealei (Fort.) Carr. Using Supercritical Fluid Chromatography with Chemical Pattern Recognition
The established model demonstrated that the developed SFC coupled with PLS-DA method showed a great potential application for quality assessment of M. bealei.
Identification of Salvia species using high-performance liquid chromatography combined with chemical pattern recognition analysis.
The results showed that all of the samples were correctly classified both in partial least squares discriminant analysis and hierarchical cluster analysis based on the four compounds (caffeic acid, rosmarinic acid, salvianolic acid B, and salvianolics acid A).
Recent quantitative research of near infrared spectroscopy in traditional Chinese medicine analysis
An overview of experimental conditions investigated in NIRS for TCM components that are related to individual compounds such as lipids, essential oils, phenolics, alkaloids, saponins and carbohydrates and their potential in the separation of TCMs is described.
