[Studies on the chemical constituents of Rhodiola dumulosa (II)].
The rhizoma samples of Rhodiola dumulosa were cut into fragments and extracted by 95% EtOH. This extract was successively extracted with Et2O, EtOAc, n-BuOH. Five compounds were obtained from the EtOAc fraction. The structures were identified as beta-sitosterol glucoside (I), chrysophanol-8-O-beta-D-glucopyranoside (II), rhodionin (III), crenuloside (IV), herbacetin-7-O-(3"-beta-D-glucopyranosyl)-alpha-L-rhamnoside (V). Chrysophanol-8-O-beta-D-glucopyranoside and crenuloside of compounds were obtained from this plant for the first time, and chrysophanol-8-O-beta-D-glucopyranoside was obtained from Rhodiola Linn for the first time.
