Triterpenoid saponins from Neonauclea sessilifolia Merr.
Two new triterpenoid saponins, quinovic acid 3-O-6-deoxy-beta-D-glucopyranoside, 28-beta-D-glucopyranosyl ester and quinovic acid 3-O-alpha-L-rhamnopyranosyl-(4 --> 1)-beta-D-glucopyranoside, along with three known saponins, have been isolated from the EtOAc extracts of the dried stems of N. sessilifolia Merr. Structure elucidation of 1-3 was based on NMR, MS, IR and chemical analysis.
