Abstract

Abstract: Two new saponins were isolated from Glycyrrhiza yunnanensis Cheng f.et L.K.Tai.On the basis of chemical and spectral evidence, their structures were elucidated as 3β-hydroxy-olean-11, 13-dien-29-oic acid-3-O-β-D-glucuropyranosyl(1-4)-β-D-glucuropyranoside and 3β, 21α-di-hydroxy-Olean-11, 13-dien-29-oic acid-3-O-β-D-glucuropyranosyl (1-4)-β-D-glucuropyranoside anddesignated as yunnanglysaponin A and B respectively.
