[Studies on the chemical constituents from Rhodiola dumulosa (I)].
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. Six compounds were obtained from the Et2O fraction. The structures of six compounds were identified. The compounds are beta-sitosterol (I), herbacetin-8-methyl ether (II), kaemperol (III), kaemperol-7-O-alpha-L-rhamnoside (IV), beta-sitosterol glucoside (V), herbacetin-7-alpha-L-rhamnoside (VI). beta-sitosterol, herbacetin-8-methyl ether and kaemperol of compounds were obtained from this plant for the first time.
