Chemical Characterisation of the Essential Oil of Hypericum aviculariifolium Jaub. & Spach subsp. depilatum (Freyn & Bornm.) Robson var. bourgaei (Boiss.) Robson from Turkey

The genus Hypericum L. is represented by 96 species, 47 taxa being endemic for Turkey. The study material of this present work Hypericum aviculariifolium Jaub. & Spach subsp. depilatum (Freyn & Bornm.) Robson var. bourgaei (Boiss.) Robson (Clusiaceae) is also endemic. The essential oil was obtained by hydrodistillation of the aerial parts collected from Antalya, Turkey. Essential oil was analysed both by GC and GC/MS, simultaneously. Hexadecanoic acid (28.0 %), lauric acid (11.3%), myristic acid (9.7%) and caryophyllene oxide (8.7 %) were found as the main constituents.  To the best of our knowledge, this is the first study on the essential oil chemistry of this plant.
