Abstract:
OBJECTIVETo study the chemical constituents of Memorialis hirta.
METHODCompounds were isolated and purified by multiple methods, and their structures were identified based on physicochemical property and spectrum data.
RESULT12 compounds were isolated from ethyl acetate from 95% ethanol extracts of M. hirta, they were isorhamnetin (1), kaempferol (2), quercetin (3), isorhamnetin-3-O-alpha-L-rhamnopyranoside (4), kaempferol-3-O-alpha-L-rhamnopyranoside (5), isorhamnetin-3-O-beta-D-glucopyranoside (6), kaempferol-3-O-beta-D-glucopyranoside (7), quercetin-3-O-alpha-L-rhamnopyranoside (8), quercetin-3-O-beta-D-glucopyranoside (9), isorhamnetin-3-O-rutinoside (10), kaempferol-3-O-rutinoside (11) and quercetin-3-O-rutinoside (12), respectively.
CONCLUSIONAll compounds were obtained from the genus Memorialis for the first time.
