To investigate the chemical constituents of the bark of Caragana opulens.
The constituents of the CH3Cl-soluble portion in the 95% ethanol extract were isolated and purified by means of chromatography. The compounds were identified by their physical characteristics and spectral features.
Eight compounds were isolated and identified as encelin(1), (+)-13-Hydroxyspathulenol(2), (+) -3alpha,9beta-aromaden dranediol(3), quercetin(4), penduletin(5), lupenol(6), Lup-20(29) -en-3-one (7), beta-sitosterol(8).
Compounds 1, 2, 5, 7 are isolated for the first time from Caragana genus.
