A new 3α-acetoxy-urs-23,28,30-trioic acid from the leaves of Acanthopanax Trifoliatus

Abstract

A new 3α-acetoxy-urs-23,28,30-trioic acid, named acantrifoic acid B (1), has been isolated from the leaves of Acanthopanax trifoliatus. Its chemical structure has been characterized on the basis of spectral and chemical evidence. Journal of Chemistry, Vol. 42 (1), P. 121 - 124, 2004
