Chemical composition of the essential oil of endemic Heracleum platytaenium BOISS. (Apiaceae) growing wild in Turkey Türkiye’de doğal olarak yetişen endemik Heracleum platytaenium BOISS. (Apiaceae)’nin uçucu yağının kimyasal bileşimi

In this study, the essential oils of endemic Heracleum platytaenium (Apiaceae) species in Sinop region of northern Turkey  were investigated and 27 components were identified by GC, GC-MS. Essential oils were obtained by Clevenger-type hydrodistilled from the aerial parts of plants collected from the natural habitats. The essential oils yield is very low and 0.5 (v/w). Twenty seven constituents were comprised the 98.89% of the total essential oil extracted from the Heracleum platytaenium . The predominant compounds of Heracleum platytaenium were as Limonene (30.83%), Terpinolene (17.98%), β-Pinene (16.36%) and Ocimene (13.68 %). The results were discussed in view of chemotaxonomy and natural products.
