A diverse array of sources and preparative procedures are available to obtain organic carotenoids. - Lutein may be extracted from the petals of the Mexican marigold (Tagetes erecta) (Fig. 7.32). [69] Since xanthophyils occur in Nature mostly as esters, and while the free alcohol form is advantageous for many applications, the extraction process with a hydrocarbon is often followed by a hydrolytic step. [63]... 

Other carotenoids such as lycopene from tomato and its industrial waste [65-68] and lutein esters from marigold (Tagetes erecta) petals [69-71] had been extracted with supercritical fluids, achieving better extractiOT yields when modifiers and cosolvents were used as acetone, chloroform, ethanol, and vegetable oils.
