In cooked (orange) carrots beta-carotene content (1890 mcg) was found much higher than in raw carrots-(1045 mcg/100 g). Heat processing of carrots affected alpha- and beta-carotene contents; their value decreased (3.7; 5.3) in water blanching, whereas increased (5.8; 8.2) in steam blanching compared to that in fresh carrots (5.2; 8.1 mg/100 g) respectively.
An interferon inducer has been isolated from carrot. It stimulates cells to produce the protein that increases human resistance to virus infections.

The British Herbal Pharmacopoeia recommends Daucus carota Linn. (wild carrot) for its diuretic activity.

The fura-nocoumarins, 8-methoxypsoralen and 5-methoxypsoralen are found in the plant. The seed oil contains terpinen-4-ol, a renal irritant. It is believed to cause diuretic activity.
croorganisms and insects, apparently due to the presence of the volatile principle which possesses bacteriostat-ic and toxic properties.
The root, on steam distillation, gave 4-O-methyl-resorcylaldehyde in a concentration of 0.8%. (The growth of E. coli was arrested by the aldehyde in 0.041% concentration; fish died within 4 min in 0.02% solution.) The sterols consists mainly of stagma and brassica sterols. Alpha-amyrin and lupeol, both free and as esters are also present in the root.
The plant contains lupeol, beta-amyrin 2-hydroxy, 4-methoxy benzaldehyde, and ferulic acid.
