| Hazard Information | Back Directory | [Chemical Properties]
Dark purple crystals, sensitive to oxygen and light. Insoluble in water, very slightly soluble in ethanol, slightly soluble in vegetable oils, and soluble in chloroform. Available as a commercial product only, it may contain other carotenes. For dilution and improved stability, it can be dissolved in vegetable oils and fats to form a solution or emulsion, and may contain varying ratios of cis/trans isomers. | [Uses]
Citranxanthin is an antioxidant β-carotene (C184250) found in plants such as tomatoes, kale and papaya, as well as in the yolks of fertile chicken eggs. | [Definition]
ChEBI: An apo carotenoid compound arising from oxidative degradation of the beta,beta-carotene skeleton at the 1'- and 6'-positions. | [Purification Methods]
Purify it by chromatography on a column of 1:1 MgO and HyfloSupercel (diatomaceous filter aid). Crystallise it from pet ether. Store it in the dark under N2 or Ar at 0o. Crocetin diethyl ester (8,8'-diapo- |
