Triterpenoid Saponins from the Fruits of Akebiae quinata

Abstract

Three new triterpenoid saponins together with eight known compounds have been isolated from the fruits of Akebiae quinata. On the basis of the spectroscopic and physiochemical evidence, the new compounds were elucidated as 3-O-β-D-xylopyranosyl-(1→2)-α-L-arabinopyranosyl gypsogenin, 3-O-α-L-rhamnopyranosyl-(1→2)-α-L-arabinopyranosyl gypsogenin and 3-O-β-D-xylopyranosyl-(1→2)-α-L-arabinopyranosyl-28-O-β-D-glucopyranosyl-(1→6)-β-D-glucopyranosyl gypsogenin.
