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 alpha-copaene (18.0%), beta-caryophyllene (17.8%), and delta-cadinene (14.7%). The sweet bisabolane sesquiterpenoid, hernandulcin, formed only 1.1% of the leaf oil.
