[Oleoresin of Aucoumea klaineana.].
From oleoresin of Aucoumea klaineana Pierre, five triterpenes are isolated; one pentacyclic triterpene: alpha-amyrin and four tetracyclic triterpenes: masticadienediol which seems to be new in this family, 3alpha-hydroxytirucalla-8,24-dien-21-oic acid, 3 alpha-hydroxytirucalla-7,24-dien-21-oic acid which have been already isolated in some Burseraceae and 3-oxotirucalla-7,24-dien-21-oic acid which seems to be a new triterpene.
