Abstract

Investigation of the chloroform extract of Bursera arida (Burseraceae) resulted in the isolation of a new pentacyclic triterpene hemiketal which was named benulin. On the basis of biogenetic considerations and physical and chemical data, benulin was postulated to be 3α-hydroxy-3,25-epoxylup-20(29)-en-28-oic acid. This structure was confirmed by an x-ray study of benulin.
