Abstract

The essential oils of wild and cultivated forms of Lippia adoensis Hochst. ex Walp. collected in Ethiopia were examined by GC and GC/MS. The oils from both forms were found to differ in their physical characteristics and chemical composition. Fourteen compounds representing 88–95% of the oil from the cultivated plants and sixteen compounds constituting 68–86% of the oil from the wild plants were identified. Linalool, which was absent in the oil of the wild form, is the major component (68.06–82.57%) in the oil of the cultivated form. Also limonene (3.44–32.73%), perillaldehyde (0.04–26.90%) and piperitenone (0.15–44.48%) are found in oils from the wild plants but not in oils from the cultivated plants. The uncommon monoterpene ketone, 2-methyl-6-methylene-2, 7-octadien-4-one (ipsdienone), was found in the oils of the cultivated plants (0.06–0.81%) and the wild plants (0.81–14.89%). © 1993 Allured Publishing Corp.
