A new 3,4-seco-lupane-type triterpenoid from the pulp of Acanthopanax senticosus (Rupr. et Maxim) Harms

Abstract

A new triterpenoid, 3,4-seco-lupane-20(29)-ene-3,28-dioic acid (1), together with three known lignans, (−)-schisandrin B (2), (−)-sesamin (3) and (−)-syringaresinol (4), was isolated from the pulp of Acanthopanax senticosus (Rupr. et Maxim) Harms. Their structures were elucidated by means of physicochemical properties and spectroscopic methods (1D, 2D-NMR and MS).
