Chemical Composition of the Essential Oil of Stachys byzanthin C. Koch. from Iran

Abstract

The chemical composition of the oil obtained by hydrodistillation of the aerial parts of Stachys byzanthina C. Koch, was investigated by GC and GC/MS analysis. Twenty-four components representing 88.5% of the total oil were identified, of which sesquiterpenes—alpha;-copaene (16.5%), spathulenol 16.1%), β-caryophyllene (14.3%) and β-cubebene (12.6%)—were the major components.
