Abstract: Flavonoids were separated from Chinese tallow leaf (CTL) using silica and sephadex LH-20 gel columnchromatography, identified their purity and analyzed quantitatively using HPLC, analyzed quanlitatively using UV,IR,NMR,LC-MS. The results showed that CTL flavonoids consist of quercetin, kaempferol and their glycosides. Contents (g/100g drymass) of quercetin, kaempferol and quercetin glycoside are 0.0965, 0.1232,0.6975 in CTL respectively.
