## Abstract A mixture of two slowly interconverting isomeric compounds was isolated from __Bernardia laurentii__ and identified as the __trans__โ€ and __cisโ€p__โ€hydroxycinnamoyl esters of the triterpene taraxerol. Their ^13^C and ^1^H NMR spectra were totally assigned with the aid of concerted twoโ€d
