The investigation of chemical constituents in stem bark and root of Calophyllum apetalum (Guttiferae) led to isolate sixteen xanthones and two coumarin derivatives. Among them, two linear pyranoxanthones [caloxanthones I (1) and J (2)] from the stem bark, and two xanthones [caloxanthone K (1 0) and 1,3,6,8-trihydroxy-2-methoxyxanthone (1 2)] from the root were new ones. The respective structures were determined by the spectral analysis.
