Daucus carota Umbelliferae

In carrot, Daucus carota (Umbelliferae), 6-methoxymellein was identified as a phytoalexin (Figure 29). It is biosynthesized by 6-hydroxymellein-O-methyltransferase from 6-hydroxymellein, which is biosynthesized from 1 mol of acetyl coenzyme A (CoA) and 4 mol of malonyl-CoA by a polyketide biosynthetic enzyme, 6-hydroxymellein hydroxylase.2 ...

Isodaucanes such as (+)-6,10-epoxy-7(14)-isodaucene and 7(14)-isodaucen-10-one are constituents of the oil of sage from Salvia sclarea (Labiatae). The name dau-cane stems from the carrot Daucus carota (Umbelliferae), from which (+)-4,8-daucadiene, (+)-8-daucen-5-ol and (-)-5,8-epoxy-9-daucanol have been isolated. 

Connecting the bonds C-l-C-6 and C-6-C-10 in famesane formally produces the spiro[4,5]decane basic skeleton of acorane. The name of this class of sesquiterpenes stems from the Acorus species. (-)-4-Acoren-3-one, for example, has been isolated from Acorus calamus (Calamus, Araceae) and from the carrot Daucus carota (Umbelliferae). The oil of calamus (oil of sweet flag) from the rhizome of Acorus calamus with its warm and spicy odor and pleasant bitter taste is predominantly used in perfumery and as a minor (possibly carcinogenic) ingredient of vermouth, some flavored wines and liqueurs. (+)-3,7(ll)-Acoradiene is a constituent of juniper Juniperus rigida its enantiomer occurs in Chamaecyparis nootkatensis (Cupressaceae). 

About 200 naturally abundant tetraterpenes are known to date and referred to as carotenoids because all of them represent structural variants or degradation derivatives of p-carotene from the carrot Daucus carota (Umbelliferae) with 11 to 12 conjugated CC double bonds. The generally accepted parent name is "carotene" two Greek letters (p, y, s, 9, k, % and /) define all seven of the known end groups.

The cicutoxin-like compounds are known for their extreme and violent toxicity. There are other plant species that contain these polyacetylene type compounds, however none are as toxic as cicutoxin and oenanthotoxin. These species all come from the Umbelliferae family and include Falcaria vulgaris, Slum sisarum, Carum carvi, Aegopodium podagraria and Daucus carota. Daucus carota is the common carrot and it contains a similar cicutoxin-like compound, caratotoxin, but is less toxic (LD50 = 100 mg/kg i.v. in mice) than cicutoxin. Caratotoxin is found in minute amounts in carrots and is not considered a health concern for humans (Crosby and Aharonson, 1967).

Carrot Seed Oil occurs as a light yellow to amber liquid having a pleasant, aromatic odor. It is the volatile oil obtained by steam distillation from the crushed seeds of Daucus carota L. (Fam. Umbelliferae). It is soluble in most fixed oils, and is soluble, with opalescence, in mineral oil. It is practically insoluble in glycerin and in propylene glycol.
