It is important in the xanthophyll cycle.Synthesized in plants and some micro-organisms, it is the pigment that gives paprika (made from bell peppers), corn, saffron, wolfberries, and many other plants and microbes their characteristic color.. Xanthophylls are very polar as they contain alcohol, ketone, aldehyde, acid, or epoxide groups, and thus may be extracted with ethyl alcohol or mixtures of ethyl alcohol and comparatively less polar solvents, such as chloroform (Houghton and Raman, 1998).
