Abstract: The estersoluble fractions of the aerial parts of Stellera chamaejasme L.was studied by using chromatography techniques.The structures of the purified compounds were elucidated on the basis of spectral data and chemical evidences,they were determined as 1-linoloyl-3-palmitoylglycerol(1),linolenic acid(2),linoleic acid(3), β-sitosterol(4),ethyl linolenate (5),daphnoretin(6),isoneochamaejasmin A(7),monoethyl malonate(8),umbelliferone(9),neochemaejasme B(10) and 2,5-dihydroxybenzoic acid(11).Compounds 1,8 and 11 were obtained from S.chamaejasme L.for the first time.
