Carotenoids extraction and quantification was carried out from flowers of Yellow bloom, flame tree, Gerbera, yellow rose, solid aster and Golden aster. Six solvents viz., Hexane, acetone, ethanol, Chloroform, Petroleum ether and diethyl ether were used for extraction of carotenoids. The extracted carotenoids were quantified using UV-visible spectrophotometer by comparison with standard carotenoids. There are significant differences in the distribution of carotenoid components depending on the color, nature, and variety of selected flowers. Among the various carotenoids analyzed xanthophyll violaxanthin was found to have maximum concentration 12 μg/g, in Yellow bloom flowers. In Gerbera, the carotenoid antheraxanthin was found to possess the higher concentration of 11.91μg/g. The carotenoid auroxanthin obtained from ethanolic extracts has the higher concentration of 48.64 μg/g, 10.2μg/g, 22.1 μg/g, 29.1 μg/g from flowers of flame tree, yellow rose, solid aster and Golden aster respectively. © 2016, Global Research Online.
