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.
