| chemical characterization and biological activity of essential oils from daucus carota l. subsp. carota growing wild on the mediterranean coast and on the atlantic coast. | the essential oils and supercritical co(2) extracts of wild daucus carota l. subsp. carota growing spontaneously in sardinia and in portugal were investigated. the main components in the sardinian essential oil of flowering and mature umbels with seeds are beta-bisabolene (17.6-51.0%) and 11-alpha-(h)-himachal-4-en-1-beta-ol (9.0-21.6%); instead, the oils from portuguese samples are predominantly composed of geranyl acetate (5.2-65.0%) and alpha-pinene (3.5-37.9%). supercritical extracts contain ... | 2009 | 18950693 |
