Abstract

Two new triterpenoid saponins, puberosides A and B, were isolated from the aerial parts of Glochidion puberum. Their structures were elucidated as 3α-[(O-β-d-glucopyranosyl-(1 → 3)-O-α-l-arabinopyranosyl)oxy]-22α-benzoyloxy-olean-12-ene-16α,28-diol (1) and 3α-[(O-β-d-glucopyranosyl-(1 → 3)-O-α-l-arabinopyranosyl)oxy]-28-benzoyloxy-olean-12-ene-16α,22α-diol (2) by analysis of their spectroscopic data.
