摘要：

A novel pentacyclic triterpenoid, 2 beta-hydroxy-3-oxo-D: A-friedoolenanan-29-oic acid has been isolated from the methanol extract of the stem bark of Dichapetalum barteri, and characterised by spectroscopic methods. Also reported for the first time from the plant are two lupane-type triterpenoids betulinic acid and betulonic acid, the friedelane triterpenoids syn: canophyllal, syn: canophyllol, friedelan-3-one and friedelan-3 alpha-ol (epifriedelinol), the more common triterpenoids beta-sitosterol and stigmasterol, as well as seven long chain esters of ferulic acid.
