Title: Study on flavonoid chemical constituents contained in Memorialis hirta
Abstract: To study the chemical constituents of Memorialis hirta.Compounds were isolated and purified by multiple methods, and their structures were identified based on physicochemical property and spectrum data.12 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.All compounds were obtained from the genus Memorialis for the first time.
