外文摘要：In the current work,a novel triterpene saponin,named ursolic acid 3-O-[α-L-rhamnopyranosyl(1''→6')]-β-D-glucopyranosyl-28-O-β-D-glucuronopyranoside(1),together with two known fiavonol glycosides,kaemferol 3-O-α-L-rhamnopyranoside(2)and quercetin 3-O-β-D-glucopyranoside(3),was isolated from the stem outer barks of Pinus pumila by repeated column chromatography and vacuum liquid chromatography.The chemical structures of the secondary metabolites 1-3 were characterized by their spectroscopic data and other physico-chemical evidence,as well as by comparison with the literature.The secondary metabolites 2 and 3 were found in this species for the first time.
