The essential oils obtained by hydrodistillation fr om the aerial parts of Hypericum perforatum L. and Hypericum scabrum L. from plants growing wild i n Tajikistan were analyzed by GC-MS. Sixty-six compounds were identified in the essentia l oils of H. perforatum with germacrene D (13.7%), α -pinene (5.1%), (E)-caryophyllene (4.7%), n-dodecan ol (4.5%), caryophyllene oxide (4.2%), bicyclogermacrene (3.8%), and spathulenol ( 3.4%) as the main constituents. Twenty-six components were identified in the oil of H. scabrum L. with α -pinene (44.8%), spathulenol (7.1%), verbenone (6.0%), trans-verbenol (3.9%), an d γ -muurolene (3.5%) as the most abundant components. A cluster analysis based on the major components of H. perforatum reveals a large degree of variability in composition of samples fro m different geographical locations.
