摘要：

Six new xanthones, caloxanthone F, G, H, 6-hydroxy-1,3,5-trimethoxy-, 3,6-dihydroxy-1,5-dimethoxy- and 1,3,6-trihydroxy-5,7-dimethoxyxanthone, were isolated from the stem wood of Calophyllum austroindicum, in addition to eight known xanthones. From the bark, four known xanthones, a coumarin, apetallic acid, and (-)-epicatechin were isolated. These structures were determined by analysis of NMR spectral data including 2D techniques.
