Original Source: Quercetin 3-rhamnoside Exerts Antiinfluenza A Virus Activity in Mice.
Our previous report showed that quercetin 3-rhamnoside (Q3R) possessed antiviral activity against influenza A/WS/33 virus in vitro. The present study evaluated the effect of Q3R on influenza A/WS/33 virus infected mice. Mice orally treated with Q3R (6.25 mg/kg per dose) at 2 h before and once daily for 6 days after influenza virus infection showed significant decreases in weight loss, and decreased mortality. Lung virus titers of mice killed at 6 days after infection were about 2000 times lower than...

Production of Bioactive Flavonol Rhamnosides by Expression of Plant Genes in Escherichia coli.
Biotransformation of flavonoids using Escherichia coli harboring specific glycosyltransferases is an excellent method for the regioselective synthesis of flavonoid glycosides. Flavonol rhamnosides hav...
Ultrasound-assisted extraction of phenolic antioxidants from Acacia confusa flowers and buds.
Acacia confusa Merr. (Leguminosae), a species native to Taiwan, is widely distributed on the hills and lowlands of Taiwan, and has been used in traditional medicines. In this study, the application of...
Glucose intestinal absorption (GIA) is one of the factors that increase glycaemia. Its reduction could be an important factor in decreasing hyperglycemia in diabetic patients. It has been shown that t...
Three new flavonoids from the seeds of Hippophae rhamnoides subsp. sinensis.
To study the chemical constituents of the seeds of Hippophae rhamnoides subsp. sinensis, three new flavonoids acylated with one monoterpenic acid, named 3-O-β-d-glucosyl-kaempferol-7-O-{2-O-[2(E)-2,6...
Flavonoids in the grasses (Poaceae family), Arthraxon hispidus (Thunb.) Makino and Miscanthus tinctorius (Steudel) Hackel have long histories of use for producing yellow dyes in Japan and China, but u...
