Essential oil compositions of some species of Cyclotrichum and antimicrobial activities

Abstract

In this study we report on the essential oil composition of six freshly collected plant species, Cyclotrichium glabrescens (Boiss. & Kotschy ex Rech. F.) Leblebici, C. longiflorum Leblebici, C. stamineum, C. niveum, C. leucotrichum, and C. origanifolium, and their biological activity. The essential oil compositions of Cyclotrichium glabrescens and C. longiflorum and their antimicrobial activities are reported for the first time in this study. The yields of essential oils of the leaves of the species Cyclotrichium glabrescens, C. longiflorum, C. stamineum, C. niveum, C. leucotrichum, and C. origanifolium, were 0.5, 0.8, 1.2, 3.4, 1.8, and 2.3%, respectively.
