Essential oil composition of Hypericum uniglandulosum Hausskn. ex Bornm. and Hypericum lydium Boiss. from Turkey

Abstract

Hypericum uniglandulosum Hausskn. ex Bornm. and Hypericum lydium Boiss. are growing naturally in the Eastern Anatolian region of Turkey and both are represented in the same section, Drosanthe Robson. The essential oils obtained by hydrodistillation from the aerial parts of Turkey native H. uniglandulosum and H. lydium were analyzed by GC, GC–MS. Twenty-six compounds were identified in the essential oils of H. uniglandulosum with pinene (35.1%), undecane (19.2%), benzoic acid (2.7%) and cyclohexasiloxane (2.3%) as main constituents. Fifty-one components were identified in the oil of H. lydium with pinene (58%), pinene (%5.10) and myrcene (3.1%) as the most abundant components. The essential oil compositions of both species have given some clues on the chemotaxonomy of genus and as a resource of natural product
