Abstract:
OBJECTIVETo investigate the chemical constituents of the aerial parts of Polygala sibirica systematically.
METHODSThe chemical constituents were isolated by various column chromatographic methods. The structures were identified by spectral data.
RESULTTen compounds were isolated and identified as 6-hydroxy-1, 2, 3, 7-tetramethoxy xanthone (1); 1, 2, 3, 6, 7-heptamethoxy xanthone (2); 1, 7-didydroxy-2, 3-methylenedioxy xanthone (3); 1, 7-dihydroxy-2, 3-dimethoxy xanthone (4); 1, 3, 7-trihydroxy-2-methoxy xanthone (5); 1, 6, 7-trihydroxy-2, 3-dimethoxy xanthone (6); alpha-spinasterol (7); alpha-spinasterolic-3-O-beta-D-glucoside (8); squalene (9) and polygital (10).
CONCLUSIONCompounds 1-10 were isolated from this species for the first time.
