Chemical investigation of Ceylonese plants. Part 20. Extractives of Mesua myrtifolia. Isolation and structure of a new triterpene hydroxy-acid, myrtifolic acid

Abstract

From the bark extractives of Mesua myrtifolia(a Malaysian species) simiarenone, simiarenol, taraxerol, betulinic acid, and a new triterpene acid, myrtifolic acid, have been isolated. The latter has been correlated with bauerene and identified as 3α-hydroxybauer-7-en-28-oic acid. From the timber extractives myrtifolic acid, oleanolic acid, and jacareubin have been obtained.
