Six pentacyclic triterpenes were isolated as their methyl ester from the methylated rootwood extracts of Musangacecropioides and their structure elucidated by 2D-COSY spectroscopic methods. They were methyl tormentate, methyl 2-acetyltormentate, methyl 28-glucosyltormentate, methyl pomolate, methyl euscaphate and a new pentacyclic triterpene, methyl cecropioate (methyl 2α,11α-diacetoxy,3β,19α-dih
