Abstract

We have previously reported three new oleanene-type glycosides and kudzusaponin $A_3$ methyl ester and subproside II methyl ester from the roots of Echinosophora koreensis. Further study has now led to the isolation of three known oleanen-type glycosides. sophoraflavoside I, azukisaponin V, and kudzusaponin $SA_3$ as their methyl esters. The structures of theses compounds were characterized by spectroscopic and chemical methods.
