摘要	In vitro antioxidant activities of three sweet dihydrochalcone glucosides from the leaves of Lithocarpus pachyphyllus (Kurz) Rehd. (Fagaceae), trilobatin 2(n)-acetate (1), phloridzin (2) and trilobatin (3), were investigated. The IC50 (50% inhibitory concentration) values for compounds 1-3 of lipid peroxidation in rat liver homogenate were 261, 28, 88 mum, respectively. Compounds 1-3 increased superoxide dismutase (SOD) activity with EC50 (50% effective concentration) values of 575, 167, 128 mum, and glutathione peroxidase (GSH-Px) activity with EC50 values of 717, 347, 129 mum, respectively, and showed only weak DPPH (1,1diphenyl-2-picrylhydrazyl) radical scavenging activity.
