Abstract: | A method is described for isolating phosphatidylinositol (PI) from a lipid extract of soybean phosphatides. The method includes the separation of the extract with the aid of a Büchner funnel and alumina into two fractions — choline-containing phospholipids and a PI fraction — and the purification of the latter on a column of DEAE-cellulose. As a by-product, phosphatidylethanolamine with a chromatographic purity of 95–96% is obtained from the PI fraction.Institute of Marine Biology, Far Eastern Scientific Center, Academy of the Sciences of the USSR, Vladivostok.
