Lipid and essential oil constituents of cota hamzaoglui Özbek & vural (Asteraceae)

Abstract

In the present work, lipids and essential oil constituents of endemic Cota hamzaoglui Özbek & Vural were investigated with GC-FID/MS techniques. The fatty acids fraction was isolated with liquid-liquid extraction from the herb with Folch method and then methylated with BF3 reagent. Linolenic, linoleic, oleic, and hexadecanoic acids were found to be the main fatty acids. The unsaturated fatty acids (66.0%) prevailed upon saturated (33.6%) ones. The essential oil was characterized with high percentage of the fatty acids (34.7%), alkanes (14.0%) and aliphatic aldehydes (8.3%). The present study is the first report on chemical composition of Cota hamzaoglui Özbek & Vural lipids and essential oil
