Abstract

The lupane-triterpene glycosides, bourneioside A and bourneioside B, and two known saponins were isolated from Lonicera bournei Hemsl. The structures of bourneioside A and B were elucidated as 3-O-beta-D-glucopyranosyl-23-hydroxy-lup-20(29)-en-28-oic acid-28-O-beta-D-glucopyranosyl ester and 3-O-beta-D-glucopyranosyl-23-hydroxy-lup-20(29)-en-28-oic acid-28-O-[beta-D-glucopyranosyl-(1 --> 6)-beta-D-glucopyranosyl] ester, respectively, on the basis of spectral data and chemical evidence.
