Abstract
The chemical composition of the essential oils obtained by hydrodistillation from the pastinocello carrot, Daucus carota ssp. major (Vis.) Arcang. (flowers and achenes), and from nine different commercial varieties of D. carota L. ssp. sativus (achenes) was investigated by GC/MS analyses. Selective breeding over centuries of a naturally occurring subspecies of the wild carrot, D. carota L. ssp. sativus, has produced the common garden vegetable with reduced bitterness, increased sweetness, and minimized woody core. On the other hand, the cultivation of the pastinocello carrot has been abandoned, even if, recently, there has been renewed interest in the development of this species, which risks genetic erosion. The cultivated carrot (D. carota ssp. sativus) and the pastinocello carrot (D. carota ssp. major) were classified as different subspecies of the same species. This close relationship between the two subspecies urged us to compare the chemical composition of their essential oils, to evaluate the differences. The main essential-oil constituents isolated from the pastinocello fruits were geranyl acetate (34.2%), α-pinene (12.9%), geraniol (6.9%), myrcene (4.7%), epi-α-bisabolol (4.5%), sabinene (3.3%), and limonene (3.0%). The fruit essential oils of the nine commercial varieties of D. carota ssp. sativus were very different from that of pastinocello, as also confirmed by multivariate statistical analyses.

Chemistry

Per 100 g, the carrot is reported to contain 86.0 g H2O, 0.9 g protein, 0.1 g fat, 10.7 g carbohydrate, 1.2 g fiber, 1.1 g ash, 80 mg Ca, 30 mg P, 1.5 mg Fe, 2,000-4,300 IU Vit. A, 60 IU Vit. B1, 3 mg niacin, and 3 mg ascorbic acid. The Wealth of India (C.S.I.R., 1948-1976) reports thiamine (56-101 ug/100g), riboflavin (50-90 ug/100 g), and nicotinic acid (0.56-11 mg/100 g) among the B vitamins. Vitamin C is in a protein-ascorbic acid complex. Vitamin D, a substance with the characteristics of vitamin E and a phospholipoid of vitamin reactions corresponding to A and D and containing calcium, phosphorus and nitrogen in organic linkage, are also present. Carrots contain ca 5.27% ZMB of phytin. Sixteen percent of the phosphorus is present as phytic acid phosphorus. The lipids extracted from raw carrots are characterised by a low nitrogen content (0.33-0.72%) and by the absence or low content (0.52%) of choline, while those extracted from steamed roots are rich in nitrogen (1.1-1.3%) and choline (4.2-4.4%). Pectin isolated from carrots (yield, 16.82-18.75% on dry weight) has no gelling property. Ash of carrots gave (on fresh weight basis): total ash, 0.92; K2O, 0.51; Na2O, 0.06; CaO, 0.07; MgO, 0.02; and P2O5, 0.09%. Trace elements reported to be present include: Fe, Al, Mn, Cu, Zn, As, Cr, I, Br, Cl, U, and Li (C.S.I.R., 1948-1976).
Toxicity

Daucus has been reported to contain acetone, asarone, choline, ethanol, formic acid, HCN, isobutyric acid, limonene, malic acid, maltose, oxalic acid, palmitic acid, pyrrolidine, and quinic acid. Reviewing research on myristicin, which occurs in nutmeg, mace, black pepper, carrot seed, celery seed, and parsley, Buchanan (J. Food Safety 1: 275, 1979) noted that the psychoactive and hallucinogenic properties of mace, nutmeg, and purified myristicin have been studied. It has been hypothesized that myristicin and elemicin can be readily modified in the body to amphetamines*. Handling carrot foliage, especially wet foliage, can cause irritation and vesication. Sensitized photosensitive persons may get an exact reproduction of the leaf on the skin by placing the leaf on the skin for awhile, followed by exposure to sunshine.

In 1963, Alexander Shulgin speculated myristicin could be metabolized to MMDA, a psychoactive drug related to MDA, in the liver.

This speculation has never been confirmed and studies with the closely related compounds asarone and safrole demonstrated that the proposed transamination reactions did not take place in humans. However, Alexander Shulgin notes in his book PiHKAL that

"Myristicin and the conjugated isomer isomyristicin are also found in parsley oil, and in dill. This was the oil that was actually shown to be converted to MMDA by the addition of ammonia by passage through an in vitro liver preparation."

As quoted, this transamination was conducted in vitro, and has yet to be proven to occur in vivo. -Wikipedia

What are these relationships between the essential oils and the amphetamines? In a word, there are some ten essential oils that have a three carbon chain, and each lacks only a molecule of ammonia to become an amphetamine. So, maybe these essential oils, or "almost" amphetamines, can serve as an index for the corresponding real amphetamine counterparts. I had originally called this family the "natural" amphetamines, but my son suggested calling them the "essential" amphetamines, and I like that. -shulgin ; PIHKAL

I have also read of the carrot's alleged myristicin content. Perhaps this relates to the alleged practice of smoking carrot foliage for purported psychoactive effect?
