| Abstract: | The composition of ethanolic (I) and gasoline (II) extracts of the cultivated microalgaChlorella vulgaris has been studied. With the aid of CC, TLC, qualitative reactions, GLC, and UVS the following classes of compounds have been detected in them. From the neutral lipids: hydrocarbons, carotenoids, traces of sterols and their esters, fatty acid esters, tri- and diacylglycerols, free fatty acids, and chlorophylls; and from the polar lipids: di- and monogalactosylglycerols, phosphatidylethanolamine, lecithin, phosphatidylinositol, phosphatidylserine, and three sphingosine bases. The polar lipids I and II made up 52.4 and 50.2% of the total, respectively. As compared with extract I, extract II was somewhat enriched with neutral lipids, including provitamins of the A group and vitamins of the F group. In the fatty acids of chlorella, 19 components were detected, the main ones being the 16:0 acid and 18:2 and 18:3 acids.Institute of the Chemistry of Plant Substances, Academy of Sciences of the Uzbek SSR, Tashkent.
