Chemical composition of two Inula L. (Asteraceae) species from Turkey

Abstract

The essential oil components of aerial parts of Inula graveolens Desf. and Inula oculus-christi L. was investigated by HS-SPME / GC-MS. Thirty six and thirty seven components were identified representing 96.9%and 97.4%oil, respectively. 1,8-cineole (22.4%), borneol (20.4%) and a-cadinol (11.8%) were detected main compounds of I. graveolens. Bornyl acetate (21.3%) p-cymene (16.6%) and b-pinene (14.8%) were found major components of I. oculus-christi. The results were discussed in terms of natural products, renewable resources and chemotaxonomy.
