Abstract

Nearly 350 Hypericum species exist on the earth, widely spreading in Europe, Asia and North Africa. 32 of 80 species growing in Turkey are endemic. The chemical composition of the essential oils obtained from the aerial parts of the H. uniglandulosum Hausskn. ex Bornm., H. scabroides Robson and Poulter, H. kotschyanum Boiss., H. salsugineum Robson and Hub.-Mor. and H. thymopsis Boiss. By using the hydro-distillation method is identified by GC and GC/ MS. Finally the results are compared with each other. The differences between the results of the H. thymopsis and H. scabroides obtained in this study and the previous studies show that the chemical compositions of the essential oils are different for the same species obtained at different locations. The essential oil compositions of these species, except for the H. thymopsis and H. scabroides are identified for the first time.
