The Identification and Quantitative Analysis of Unusual Keto-Carotenoids in Ripe Fruits of Maclura tricuspidate and Its Potential as a Valuable Source of Cryptocapsin

Molecules, 2022
Ripe fruits of Maclura tricuspidata (MT) are used as food material and a natural colorant in Korea. Although MT fruits have a deep red color due to carotenoid-like pigments, their chemical nature has not been explored in detail so far.

Absorption and cutaneous deposition of yellow pigment in male and female broilers in response to different levels of xanthophylls from Tagetes erecta

Austral Journal of Veterinary Sciences, 2017
To determine the saturation point of absorption and cutaneous deposition of yellow xanthophylls (XA) in broilers, two hundred and sixteen Ross 308 chickens (108 males and 108 females) were sorted by sex and randomly assigned to 6 dietary treatments ...

A 3-hydroxy %-end group in xanthophylls is preferentially oxidized to a 3-oxo ε-end group in mammals[S]

Journal of Lipid Research, 2015
We previously found that mice fed lutein accumulated its oxidative metabolites (3′-hydroxy-ε,ε-caroten-3-one and ε,ε-carotene-3,3′-dione) as major carotenoids, suggesting that mammals can convert xanthophylls to keto-carotenoids by the oxidation of ...
