Abstract

Three new naturally occurring phenylpropenoyl derivatives, sodium dupracine (1), (E)-dupracine methyl ester (2), (Z)-dupracine methyl ester (3), together with eight known compounds, were isolated from the leaves of Petasites formosanus. Their structures were established by spectral methods and chemical transformations. The isolated compounds showed significant antioxidative activity in DPPH radical scavenging assay.
