Puberosides C-E, triterpenoid saponins from Glochidion puberum

J Asian Nat Prod Res. 2011 Sep;13(9):838-44. doi: 10.1080/10286020.2011.598148.

Abstract

Three new triterpenoid glycosides, named puberosides C-E (1-3), were isolated from the water-soluble fraction of Glochidion puberum (Linn.) Hutch. Their structures were determined as 3α-[(O-β-d-glucopyranosyl-(1 → 3)-O-α-l-arabinopyranosyl)oxy]-22α-trans-cinnamoyl-olean-12-ene-16α,28-diol, 3α-[(O-β-d-glucopyranosyl-(1 → 3)-O-α-l-arabinopyranosyl)oxy]-22α-cis-cinnamoyl-olean-12-ene-16α,28-diol, and 3α-[(O-β-d-glucopyranosyl-(1 → 3)-O-β-d-glucopyranosyl)oxy]-22α-benzoyloxy-olean-12-ene-16α,28-diol by the combination of 1D, 2D NMR, and MS spectral analyses.
