Chemical Composition of Endemic Inula macrocephala Boiss. and Kotschy ex Boiss. from Turkey

Abstract

The essential oil components of aerial parts of Inula macrocephala Boiss. and Kotschy ex Boiss. was investigated by GC and GC-MS. The yield of oil is ca. 0.13 mL/100 g. Thirty five components were identified representing 90.7 % oil. Borneol (26.4 %), beta-caryophyllene (15.3 %), p-cymene (10.2 %) and bornyl acetate (8.9 %) were identified major components of plant. The results were discussed in terms of natural products, renewable resources and chemotaxonomy.
