It has been reported that carrot seeds are rich in antioxidants (Yu et al., 2005) and contain a lot of active ingredients such as camphene, b-pinene, a-pinene, myrcene, sabinene, y-terpinene, limonene, b-bisabolene, geranyl acetate, and carotol.
Carrot seed oil, which comprises 45% carotol and 6% daucene, was purchased from a commercial company.

Steam distilled carrot seed oil typically contains significant amounts of the sesquiterpene alcohol carotol (<67%) and the monoterpenoid ester geranyl acetate (<25%) (Figure 3), with highly variable amounts of the monoterpenoids alpha-pinene (2-25%), sabinene (<32%) and linalool (<6%), and of the sesquiterpenoids P-bisabolene (<16%) and daucol (<10%) (13,14,15,16) Three flavones, luteolin, luteolin 3'-O-P-D-glucopyranoside and luteolin 4'-O-P-D-glucopyranoside have been isolated from a methanol extract of carrot seed.
The major constituent of the non-oxygenated compounds was [gamma]-cadinene constituting 22.75%, the non-oxygenated compounds were divided into terpenoids (90.5%) and hydrocarbons (0.35%), while the major constituent of the oxygenated compounds was a hydroxylated compound phenyl-tert-butanol constituting 2.01%, followed by carotol (0.94%).
Caryophyllene oxide (12.06%) was the principal component of the oil followed by other major components such as palmitic acid (6.06%), carotol (3.87%), camphor (3.12%), hexahydrofarnesyl acetone (2.81%), estragole (2.47%) and linalool (2.41%) (Fig.
