Carotenoid pigments of Badami mango fruit

Carotenoid pigments of Badami mango fruit.

The only attempt at the isolation of carotene from mango fruit seems to have been made by Yamamoto Osima & Goma (1932) who obtained 60 mg. of a crystalline preparation from 38 kg., of fresh fruit pulp. From a study of its optical activity and absorption spectrum they concluded that it was a mixture of aand P-carotenes, which were, however, not separated. The inconclusive nature of their data ha...

Carotenoid pigments in GAC fruit (Momordica cochinchinensis SPRENG).

The carotenoids in Gac fruit (Momordica Cochinchinensis spreng) were analysed by high-performance liquid chromatography (HPLC), and the concentrations of beta-carotene, lycopene, zeaxanthin and beta-cryptoxanthin were measured. Lycopene was found to be predominantly present in the Gac seed membrane at a concentration of up to 380 microg/g of seed membrane. The concentration of lycopene in the G...

Carotenoid Pigments: Supercritical Fluid Chromatography

Carotenoids are one of the main classes of natural pigments and are found in a large number of fruits and vegetables (oranges, tomatoes, carrots) and in leaves where their presence is masked by chlorophylls until autumn. They are also found in some animal products (eggs, milk) and seafoods. Typically, carotenoids contain eight isoprenoid units bonded such that the units are reversed at the cent...

A novel carotenoid cleavage activity involved in the biosynthesis of Citrus fruit-specific apocarotenoid pigments

Citrus is the first tree crop in terms of fruit production. The colour of Citrus fruit is one of the main quality attributes, caused by the accumulation of carotenoids and their derivative C30 apocarotenoids, mainly β-citraurin (3-hydroxy-β-apo-8'-carotenal), which provide an attractive orange-reddish tint to the peel of oranges and Mandarins. Though carotenoid biosynthesis and its regulation h...
