Xanthophyll - Wikipedia
网页Xanthophylls (originally phylloxanthins) are yellow pigments that occur widely in nature and form one of two major divisions of the carotenoid group; the other division is formed by the carotenes.
Xanthophylls: What are Xanthophylls? | Journal Of Nutrition
网页Xanthophylls are a type of pigment found in plants, algae, and certain bacteria that belong to a larger group of compounds known as carotenoids. They are responsible for the yellow and orange colors seen in many fruits, vegetables, and flowers. Xanthophylls are lipophilic molecules, meaning they are soluble in fats and oils.
Xanthophyll: Health benefits and therapeutic insights
网页2020年1月1日 · Xanthophylls constitute a major part of carotenoids in nature. They are an oxidized version of carotenoid. Xanthophyll has widely drawn scientists' attentions in terms of its functionality, bioavailability and diversity. An assortment of xanthophyll varieties includes lutein, zeaxanthin, β-cryptoxanthin, capsanthin, astaxanthin, and fucoxanthin.

网页2018年4月7日 · Nutrient. Carotenoids are plant pigments commonly found in fruits and vegetables. They are made up of 2 classes, xanthophylls and carotenes. Whereas carotenes are composed of only carbon and hydrogen, xanthophylls include hydroxyl groups, making them slightly more hydrophilic than carotenes. Carotenoids are found throughout the body.
