The active principles of Wen-Pi-Tang possessing antioxidation and free radical-scavenging activities were isolated, and its properties were determined using the thiobarbituric acid-reactive substance (TBARS) procedure and a 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical generating system. Significant inhibitory activities against both the formation of TBARS and generation of free radicals were shown by fractions 5, 6 and 7, which contained mainly polyphenolic compounds and phenolic glycosides as… CONTINUE READING
