Abstract:
Costmary (Tanacetum balsamita L. subsp. balsamita is a very old medicinal plant which grows wild in some localities of Spain and particularly in Cantalojas, a small village of Guadalajara (Spain). Although the essential oil from this plant have been recently investigated for its insecticidal properties, we decide to reinvestigate the volatile oil of Costmary grown in Spain. The volatile oils were analyzed by gas-chromatography, 13C-NMR and 1H-NMR techniques. The oil was shown to contain carvone as main component (51.5%, 41.0% and 56.9%) together with minor amounts of beta-thujone, t-dihydrocarvone, c-dihydrocarvone, dihydrocarveol isomer c-carveol and t-carveol. It is worth noting that beta-thujone, a toxic ketone, reaches 9.8%, 12.5% and 12.1% respectively in the three samples studied.
