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.
