Chemistry of Bicyclic Sesquiterpenes Isolated from Dittrichia graveolens L. Greuter in Western Australia

Abstract

The chemistry of natural products of Dittrichia graveolens growing in Western Australia (Balingup) was investigated. These compounds were extracted using a rapid extraction technique using ethanol and aqueous solutions. The bioactivity of the extracted bicyclic sesquiterpenes acid was investigated on alfalfa seed germination. The isolated compounds costic and ilicic acid were used as starting material in semisynthesis of new compounds including new natural products.
