Essential oils isolated from the aerial parts if twit different populations of Tanacetum dolichophyllum (Kitam.) Kitam. (syn. Tanacetum longifolium Wall.) were analyzed by CC and COMS in order to determine the variation of concentration in their constituents. Plant collected from Dayara meadow (Sample 1) afforded cis-lanceol (11.8%), beta-pinene (10.7%), (E)-beta-farnesene (7.4%), alpha-bisabolol (7.2%), beta-eudesmol (5.2%) and terpinen-4-ol (5.1%) as the major constituents, whereas in the sample collected from Tungnath (Sample II) beta-endesmol (31.4%), alpha-bisabolol (10.7%) were the most abundant components billowed by neryl acetate (5.8%) and (E)-beta-farnesene (5.7%). The composition was dominated by sesquiterpene hydrocarbons and oxygen containing sesquiterpenes (49.2-71.1%). The oils are clearly different from those of all other previously reported T. dolichophyllum oils.
