Abstract
Masticadienonic acid (
E- and
Z-forms), 3α-hydroxy-7,24Z-tirucalladien-26-oic acid and two novel triterpenoids, dysoxylic acids A and B, have been isolated from the hexane extract of the wood and bark of
Dysoxylum pettigrewianum. Structures were determined using
1H,
13C and 2D NMR techniques.
