Abstract The oil of Tanacetum nubigenum Wallich ex DC. was analyzed by GC and GC/MS. In addition to 10.7% of sabinene, nearly 44% of the oil of T. nubigenum collected above 3600 m in the Kumaun region of the Indian Himalaya consisted of (-)-cis-chrysanthenol and its esters. The oil also contained â¼3% of esters of exo-6-hydroxycamphor, â¼1.6% 3,6;6,9-bisepoxyfarnesa-l,7(14),10-trienes as well as â¼3.5% of 6,9-epoxyfarnesa-l,7(14),10-trien-3-ols.
