摘要：

From the woods of Garcinia subelliptica four new xanthones, garciniaxanthone C, 1,2,5-trihydroxyxanthone, 2,6-dihydroxy-1,5-dimethoxyxanthone and 1,2-dihydroxy-5,6-dimethoxyxanthone have been isolated along with a new benzophenone derivative, 4',6-dihydroxy-2,3'4-trimethoxybenzophen Their structures have been determined on the basis of mainly spectroscopic data and some chemical reactions. Antioxidative properties of all the isolated xanthones have been evaluated in vitro using three assay systems to measure antilipidperoxidation, free radical and superoxide anion scavenging activity.
