Abstract
Two new triterpenoids were isolated from the ethanolic extract of the roots of Ampelopsis japonica (Thunb.) Makino. Their structures were defined as 3α-trans-feruloyloxy-2α-O-acetylurs-12-en-28-oic acid (1) and methyl 3α-trans-feruloyloxy-2α-hydroxyurs-12-en-28-oate (2) on the basis of spectral analysis.
