摘要：
Together with three known compounds, a new kaurane diterpene and a new echinocystic acid saponin, asterageratoidesoside A, were isolated from Aster ageratoides. Their structures were elucidated on the basis of spectral and chemical methods as 16 beta-hydroxy-17-acetoxy-(-)-kaurane-19-oic acid and 3-O-glucuronopyranosyl-echinocystic acid-28-{-D-beta-D-xylopyranosyl-(1 --> 3)-beta-D-xylopyranosyl-(1 --> 4)-[alpha-L-arabinosyl-(1 --> 3)]-alpha-L-rhamnopyranosyl-(1 --> 2)-alpha-L-arabinopyranosyl} ester.
