Three novel triterpenoids esters were isolated from the leaves of Melaleuca leucadendron in addition to the five known triterpenes ursolaldehyde, ursolic acid, 2α-hydroxyursolic acid, 3β-cis-p-coumaroyloxy-2α-hydroxyurs-12-en-28-oic acid and 3ß-trans-p-coumaroyloxy-2x-hydroxyurs-12-en-28-oic acid. The structures of the new compounds were determined by spectral methods to be 3β-cis-p-coumaroyloxy-2x-hydroxyursa-12,20(30)-dien-28-oic acid, cis- and trans- 3B-caffeoyloxy-2x-hydroxyurs-12-en-28-oic acids.
