Under the inhibition of Cu+2-induced LDL oxidation-guided fractionation, two new flavone glycosides with galloyl substitution were isolated from the dried fallen leaves of Terminalia catappa L. Their structures were established as apigenin 6-C-(2″-O-galloyl)-β-D-glucopyranoside (1) and apigenin 8-C-(2″-O-galloyl)-β-D-glucopyranoside (2), together with four known flavone glycosides, isovitexin, vitexin, isoorientin, and rutin, on the basis of spectroscopic method. Compounds 1 and 2 showed significant antioxidative effects. Their IC50 were 2.1 and 4.5 μM, respectively.
