Abstract In this study, D-galactose was used to establish a model of liver dysfunction caused by oxidative stress in mice, and the effect dandelion on improving exercise capacity mice with observed its mechanism expounded. This study examined role running ability, swimming endurance, blood biochemical indices, histopathological changes, tissue mRNA expression changes. The animal results showed ...

As a natural flavonoid in Ampelopsis grossedentata, dihydromyricetin (DHM, 2R,3R-3,5,7,3',4',5'-hexahydroxy-2,3-dihydroflavonol) was observed to increase the viability of •OH-treated mesenchymal stem cells using a MTT [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl] assay and flow cytometry analysis. This protective effect indicates DHM may be a beneficial agent for cell transplantation therapy. Mec...

A new flavonol galactopyranoside, myricetin 3-O-(2'',3''-digalloyl)-β-D-galactopyranoide (1), and 23 known constituents, including myricetin 3-O-(2''-galloyl)-β-D-galactopyranoide (2), myricitrin (3), myricetin (4), quercetin 3-O-(2'', 3''-digalloyl)-β-D-galactopyranoide (5), quercetin 3-O-(2''-galloyl)-β-D-galactopyranoide (6), hyperin (7), isoquercetrin (8), quercetin (9), kaempferol (10), ap...

Opportunistic mycoses increase the morbidity and mortality of immuno-compromised patients. Five Candida species have been shown to be responsible for 97% of worldwide cases of invasive candidiasis. Resistance of C. glabrata and C. krusei to azoles has been reported, and new, improved antifungal agents are needed. The current study was designed to evaluatethe activity of various polyphenolic com...

The fermented leaf of Ampelopsis grossedentata has been used as a beverage and folk medicine called "vine tea" in the southern region of China. In this paper, the optimum extraction conditions for the maximum recovery amounts of total flavonoids (TF), dihydromyricetin (DMY), myricitrin (MYG) and myricetin (MY) from natural Ampelopsis grossedentata leaves subjected to ultrasonic-assisted extract...

In Vietnam, the aerial parts of Ruellia tuberosa L. are used to treat stress oxidation and inflammatory symptoms in diabetes mellitus. The present study was designed determine antioxidant inhibition activities extract (RTE) those isolated compounds by column chromatography. crude ethanol ethyl acetate fraction exhibited potent activity 2,2-diphenyl-1-picryl-hydrazyl-hydrate (DPPH) 2,2-azinobis-...

In this study, we investigated the influence of mixture design on chemical profile Eugenia unifloraleaves, evaluating antioxidant and antimicrobial activities, toxic hemolytic potential, with focus improvement polyphenol’s extraction for incorporation extract in semi-solid forms antifungal action. The analysis was evaluated by UV-Vis HPLC. antimicrobial, antioxidant, activities were monitored. ...
