3'-hydroxy-Caroten-3-one is a carotenoid found in human fluids. Carotenoids are isoprenoid molecules that are widespread in nature and are typically seen as pigments in fruits, flowers, birds and crustacea. Animals are unable to synthesise carotenoids de novo, and rely upon the diet as a source of these compounds. Over recent years there has been considerable interest in dietary carotenoids with respect to their potential in alleviating age-related diseases in humans. This attention has been mirrored by significant advances in cloning most of the carotenoid genes and in the genetic manipulation of crop plants with the intention of increasing levels in the diet. Studies have shown an inverse relationship between the consumption of certain fruits and vegetables and the risk of epithelial cancer. Since carotenoids are among the micronutrients found in cancer preventive foods, detailed qualitative and quantitative determination of these compounds, particularly in fruits and vegetables and in human plasma, have recently become increasingly important.

Nigroxanthin is found in fruits. Nigroxanthin is a constituent of the ripe pods of red paprika Capsicum annuum var. longum.

Cryptocapsone is found in herbs and spices. Prepd. by Oppenauer oxidation of red paprika (ex Capsicum annuum) capsanthin and cryptocapsin (see Capsanthin KCW33-J).

2'-Dehydroplectaniaxanthin is found in mushrooms. 2'-Dehydroplectaniaxanthin is isolated from the ascomycete Aleuria aurantia (orange cup).
