Chemical Composition of Essential Oil of Senecio vernalis Waldst. Et Kit. (Asteraceae) from Turkey

Abstract

The chemical composition of essential oil of Senecio vernalis (Asteraceae) from Turkey was analyzed by GC and GC-MS system. The yield of the oil is 0.4 ml. The essential oil composition of S. vernalis was studied and thirty nine components representing 91.5 % of the total oil were identified. The main constituents of S. vernalis were beta-phellandrene (12.6 %), 1,8-cineole (9.2 %), caryophyllene oxide (7.3 %), beta-selinene (6.3 %) and limonene (6.2 %). The chemical distribution of essential oil compounds in the genus pattern were discussed in means of chemotaxonomy and natural products.
