Isolation of bergenin from Peltophorum pterocarpum flowers and its bioactivity

摘要: Abstract Increasing interest in biological activity of natural products outlined the necessity isolation bergenin from Peltophorum pterocarpum (P. pterocarpum) flowers. The present investigation comprises accompanied by important vitro antioxidant assays such as DPPH, hydroxyl radical and nitric oxide scavenging activities, ferric reducing power. aim includes DNA protection cleavage. Bergenin showed 4.47, 13.03, 8.67% activities at 100 µg/ml. It less result indicates that is a mild antioxidant. did not protect but it cleaved low concentration 10 µg/ml. P. pterocarpum flowers are cheap source they could be used
