Descrizione generale

The 5,6-epoxy structure can give rise to a wide variety of carotenoid end-groups with the plausible biosynthetic transformations of the 5,6-epoxy-ß-ring to give diverse structures such as the cyclopentane carotenoids capsanthin and capsorubin, the retro-carotenoids eschscholtz- xanthin and rhodoxanthin, allenic carotenoids like the neoxanthin and fucoxanthin, 5,6-diols like the karpoxanthin and latoxanthin, 3,6-poxides as found in eutreptiellanone and cucurbitaxanthin, the 6-hydroxy-γ-ring structure found in prasinoxanthin and nigroxanthin, as well as the 5,6-seco-5,6-dione-end-group of semi-ß-carotenone.

This paper presents an analytical strategy for a large-scale screening of carotenoids in tomato fruits by exploiting the potentialities of the triple quadrupole-linear ion trap hybrid mass spectrometer (QqQLIT). The method involves separation on C30 reversed-phase column and identification by

A validated ultrahigh-performance liquid chromatography method using 1.7 μm core-shell particles is presented for the identification and quantification of β-carotene (BC) and related cleavage products (CPs) in primary cell culture media. Besides BC, apo-4'-, apo-8'-, apo-10'-, and apo-12'-carotenals, as well

In this study HPLC-DAD-MS/MS was applied for the identification of compounds derived from (all-E)-β-carotene following epoxidation and oxidative cleavage. The consequences on the CIELAB colour parameters and antioxidant capacity (AC) were also evaluated. Five apocarotenoids, three secocarotenoids, seven Z isomers

The effect of the partial pressure of oxygen (pO2) on the antioxidant reactions of all-trans-beta, beta-carotene (BC) was investigated in a soybean phosphatidylcholine liposome system. Peroxyl radicals generated by thermolysis of azo-bis(2,4-dimethylvaleronitrile) at 37 degrees C initiated lipid peroxidation. BC
