Caryophyllene oxide (13%) and alpha -thujone (12%) were found as the main constituents of the oil of Tanacetum argenteum subsp. canum var, canum. Borneol (28%), 1,8-cineole (12%) and bornyl acetate (10%) were the major constituents of T. praeteritum subsp. praeteritum. In the oil of subsp. massicyticum, alpha -thujone (51%) and beta -thujone (10%) were characterized as the main constituents. Copyright (C) 2001 John Wiley & Sons, Ltd.
