بررسي اسانس گونه گياهي شبدر قرمز با روش GC/MS

GC/MS analyzes of essential oil from Trifolium pretense

In this work the essential oil of Trifolium pretense aerial parts was extracted by hydrodistillation in a Clevenger type apparatus and then they were analyzed by GC and GC/MS techniques. Eight components were characterized, representing 96.9% of the total components detected in the essential oil identification of the constituents of oil was made by comparison of their mass spectra and retention indices with those given in the literature and those authentic samples. The major components of essential oil were psoudoionone (47.1%), n-tridecane (20.3%) and cyclopropanemethanol (12.3%). The oil was richer in sesquiterpenes than monoterpenes.
