title: [Xanthones from leaves of Calophyllum inophyllum Linn].
abstract: To study the xanthones from the leaves of Calophyllum inophyllum Linn., several chromatography methods were employed to isolate the constituents. Investigation on the CHCl3 extract led to the isolation of a new xanthone named inophyxanthone A (1) and four known compounds, which were pancixanthone A (2), gerontoxanthone B (3), jacareubin (4) and pyranojacareubin (5). Among them, compound 2 was obtained from this plant firstly, and compound 3 was obtained for the first time from this genus. The structure of inophyxanthone A (1) was identified as 1, 3, 5-trihydroxy-2-(1, 1-dimethylallyl)xanthone by spectral analysis.
