Furocoumarins in the cultivated carrot, Daucus carota

Phenolics in cereals, fruits and vegetables: Occurrence, extraction and analysis

“…Major phenolic acids included p-hydroxybenzoic acid, syringic acid and 3 -caffeoylquinic acid (neochlorogenic acid), 5 -caffeoylquinic acid (chlorogenic acid), 3 -, 4 -and 5 -feruoylquinic acids, 3 -and 5 -p-coumaroylquinic acids, 3 ,4 -and 3 ,5 -dicaffeoylquinic acids and 3 ,4 -and 3 ,5 -diferuoylquinic acids [199,200]. The presence of coumarins, namely 6-methoxymellein and 6-hydroxymellein, was also reported in carrot tissues [201,202]. These compounds were predominantly accumulated in the periderm tissue of carrot root [47].…”

Rare trisubstituted sesquiterpenes daucanes from the wild Daucus carota

“…The seeds of D. carota are used for the treatment of swelling and tumors, while the roots are used as poultice in mammary and uterine carcinoma as well as skin cancer. Seed oil of this species afforded daucane-type sesquiterpenes (Dhillon et al, 1989;Mazzoni et al, 1999), such as trans-dauc-8-ene-4b-ol, trans-dauca-8, 11-diene, dauca-5,8-diene, acora-4,9-diene, acora-4,10-diene, carotol and daucol, furocoumarins (Ceska et al, 1986). Additional constituents include flavonoids (Gupta and Niranjan, 1982), polyacetylenes (Lund, 1992), fatty oil (Vesna et al, 1989) and b-carotene (Bicudo- De-Almeida et al, 1998).…”

Nutritional and therapeutic importance of Daucus carota- A review

“…Furanocoumarin, 8-Methoxypsoralen and 5-methoxypsoralen (0 .01-0.02 pg/g fresh weight) were isolated from the fresh plant. Their concentrations were increased in the diseased plant [78].Daucus carota essential oil yields 3% for seeds and 2.1% for leaves. A total of 48 compounds were identified in Daucus carota essential oil of leaves, 46 in seeds essential oil.…”

“…It was the first example for a natural eudesmane sesquiterpene with a hydroxymethyl group located at a methine carbon rater than a usual quaternary carbon in the two fused six-membered ring systems [87]. Daucane-type sesquiterpenes such as as trans-dauc-8-ene-4b-ol, trans-dauca-8,11-diene, dauca-5,8-diene, acora-4,9-diene, acora-4,10-diene, carotol, daucol and daucucarotol were isolated from Daucus carota [78,[87][88][89]. Ahmed et al, isolated four sesquiterpenes daucane esters, one polyacetylene, one sesquiterpene coumarin, and sitosterol glucoside from the roots of the wild Daucus carota ssp carota [90].Extracts of fresh roots and foliage of the garden carrot (Daucus carota) were analyzed for linear furocoumarins (psoralens) compared with standard psoralen, xanthotoxin, bergapten, isopimpinellin, heraclenin, and oxypeucedanin.…”
