Isolation and structure elucidation of three triterpenoid saponins from Acacia auriculiformis.
Three new triterpenoid saponins, proacaciaside-I, proacaciaside-II and acaciamine isolated from the fruits of Acacia auriculiformis, were identified as acacic acid lactone-3-O-beta-D-glucopyranosyl (1 --> 6)-beta-D-glucopyranoside, acacic acid lactone-3-O-alpha-L-arabinopyranosyl (1 --> 2)-beta-D-glucopyranoside and acacic acid lactone-3-O-alpha-L-arabinopyranosyl (1 --> 6)-2-acetamide-2-deoxy-beta-D-glucopyranoside based on their spectral properties and some chemical transformations.
