title: Two new triterpenoid saponins from Glochidion puberum.
abstract: Two new triterpenoid saponins, puberosides A and B, were isolated from the aerial parts of Glochidion puberum. Their structures were elucidated as 3alpha-[(O-beta-D-glucopyranosyl-(1-->3)-O-alpha-L-arabinopyranosyl)oxy]-22alpha-benzoyloxy-olean-12-ene-16alpha,28-diol (1) and 3alpha-[(O-beta-D-glucopyranosyl-(1-->3)-O-alpha-L-arabinopyranosyl)oxy]-28-benzoyloxy-olean-12-ene-16alpha,22alpha-diol (2) by analysis of their spectroscopic data.
