Essential oils of two lippia ukambensis Vatke chemotypes and lippia somalensis Vatke in Kenya

Abstract

The chemical composition of the essential oils of 41 samples of Lippia ukambensis Vatke were examined by CC/MS. Two chemotypes were identified on the basis of the camphor and l,8-cineole. The camphorchemo type of L. ukambensis contained camphor (37.3%) with only traces of l,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 l,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.
