Essential oil from leaves of Lippia dulcis grown in Colombia

Abstract

The chemical composition of the volatile compounds from the leaves of Lippia dulcis Trev. (Verbenaceae) from Colombia was studied by GC and GC/MS. Forty volatile compounds were identified, of which the major ones were α-copaene (18.0%), β-caryophyllene (17.8%), and δ-cadinene (14.7%). The sweet bisabolane sesquiterpenoid, hernandulcin, formed only 1.1% of the leaf oil.
