Abstract:
OBJECTIVETo study the chemical constituents from the stems and leaves of Calophyllum inophyllum.
METHODThe compounds were isolated by column chromatography on silica gel, Sephadex LH-20 and preparative TLC. Their structures were elucidated by chemical methods and NMR, MS spectroscopic data.
RESULTNine compounds were identified as 2-hydroxyxanthone (1), 4-hydroxyxanthone (2), 1, 5-dihydroxyxanthone (3), 1, 7-dihydroxyxanthone (4), 1, 3, 5-trihydroxy-2-methoxyxanthone (5), 6-deoxyjacareubin (6), amentoflavone (7), kaempferol-3-O-alpha-L-rhamnoside (8) and quercetin-3-O-alpha-L-rhamnoside (9).
CONCLUSIONCompounds 8 and 9 were isolated from the genus Calophyllum and compounds 1, 2, 4-6 were isolated from this plant for the first time.
