Volatile Components of Two Onosma Tokat Province of Turkey

Abstract

The genus Onosma L. (Boraginaceae) is represented in Turkey by 105 species (110 taxa), 53 of them and 1 variety are endemic for Turkey. Some species of Onosma are used as herbs, traditional medicine such as against burns, wounds and ailments (4,5). Hydrodistilled essential oils of the aerial parts of Onosma isaurica Boiss. & Heldr. And Onosma bulbotrichum DC. were analyzed by GC and GC-MS systems, simultaneously. The oil of O. isaurica contained hexahydrofarnesyl acetone (20.3%), phytol (19.0%), farnesyl acetone (8.1%) and neophytadiene isomer I/Tetradecanal (7.0%).as main constituents. The oil of O. bulbotrichum was characterized by the occurrence of hexahydrofarnesyl acetone (11.6%), farnesyl acetone (9.9%), hexadecanal (8.8%) E-geranyl acetone (7.4%) and neophytadiene isomer I (7.3%) as major components.
