Carrot seed oil is the essential oil extract of the seed from the carrot plant Daucus carota. The oil has a woody, earthy sweet smell[1] and is yellow or amber-coloured to pale orange-brown in appearance. The pharmacologically active constituents of carrot seed extract are three flavones: luteolin, luteolin 3'-O-beta-D-glucopyranoside, and luteolin 4'-O-beta-D-glucopyranoside.[2] Rather than the extract the distilled (ethereal) oil is used in perfumery and food aromatization. The main constituent of this oil is carotol.[citation needed]
Pressed carrot seed oil is extracted by cold-pressing the seeds of the carrot plant. The properties of pressed carrot seed oil are quite different from those of the essential oil.[3]
