Abstract:
OBJECTIVETo isolate and identify chemical constituents of Cassia alata.
METHODCompounds were separated and purified by column chromatography with silica gel and Sephadex LH-20, elucidated by spectroscopic methods including 1D and 2D NMR, IR and MS techniques.
RESULTTwelve compounds were isolated from C. alata, which were identified as chrysoeriol (1), kaempferol (2), quercetin (3), 5,7,4'-trihydroflavanone (4), kaempferol-3-O-beta-D-glucopyranoside (5), kaempferol-3-O-beta-D-glucopyranosyl-(1-->6)-beta-D-glucopyranoside (6), 17-hydrotetratriacontane (7), n-dotriacontanol (8), n-triacontanol (9), palmitic acid ceryl ester (10), stearic acid (11), palmitic acid (12).
CONCLUSIONCompounds 3-12 were isolated from C. alata for the first time.
