Comparison of Chemical Composition of Essential oil of Tanacetum longifolium from two different altitudes of Western Himalaya of Kumaun region of Uttrakhand, India

Abstract

The chemical profile of the hydro distilled essential oil obtained from the aerial parts of Tanacetum longifolium from two different attitudes of Kumaun Himalaya was analyzed by capillary GC-FID and GC-MS. The essential oils of aerial parts led to the identification of 42 constituents accounting for 93.5% and 91.7% of the total oil composition from two different altitudes and regions respectively. The α-bisabolol (7.4%) cadina-1, 4-diene (15%) β- eudesmol (24.8%) were present in one sample while γ-eudesmol (6.9%) β- eudesmol (10.4%) α-bisabolol (10.8%) were the principle components of another sample.
