Estimation of carotenoids
WebBeta-carotene was first isolated by Wackenroder in 1831, and many other carotenoids were discovered and named during the 1800s, although their structures were still unknown. Not until 1907 was the empirical formula of beta-carotene, C40H56, established by Willstatter and Mieg. The structure was elucidated by Karrer in 1930-31. WebExtraction of Chlorophyll and Carotenoids: Although chlorophyllous and carotenoid pigments may be extracted readily in organic solvents, for many algae, extraction is not complete unless the cells are ruptured. Therefore, filters should be placed with forceps into the base of a glass for drinking with 3 to 4 ml of 90% alkaline acetone solution ...
