New Russian F1 "Rubinovaya" cultivar of Daucus carota was found to be pink-colored due to biosynthesis of lycopene and β-carotene in relatively high overall level (up to 0.200 mg per 1 g of fresh weight, FW). The typical carotenoid composition of carrot roots with pink color were determined by proposed in the paper reversed-phase HPLC method. These are all-trans-lycopene (28-47 %); mixture of cis-lycopene isomers (7-10 %), all-trans-β-carotene (30-55%) and mixture of cis-β-carotene isomers (7-10 %). From chromatographic point of view carotenoids are retained in the proposed conditions by distribution mechanism due to a long chain of conjugated C=C-bonds makes this part of carotenoids planar with ability penetrate space between grafted C18 chains.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
