Abstract
The chemical composition of the essential oils of 41 samples of Lippia ukambensis Vatke were examined by GC/MS. Two chemotypes were identified on the basis of the camphor and 1, 8-cineole. The camphor chemotype of L. ukambensis contained camphor (37.3%) with only traces of 1, 8-cineole, while the other chemotype contained 1, 8-cineole (23.7%) and only 1.1% camphor. Of the twelve components which were present in both chemotypes, only eight were quantitatively significantly different. The major compound in the oil of L. somalensis was 1, 8-cineole (31.9%). By using fifteen components of L. somalensis oil, its similarities and differences with those of the two Lippia chemotypes were compared.
