| Abstract: | We have developed a high-performance liquid chromatographic (HPLC) procedure for separation of O-acetyl-N-p-nitrobenzoyl derivatives of six neutral glycosphingolipids: glucosylceramide, lactosylceramide, globotriaosylceramide, lactotriaosylceramide, globotetraosylceramide, and neolactotetraosylceramide. The recoveries of glucosylceramide and globotetraosylceramide for the derivatization procedure and HPLC analysis were approximately 75%, and one nanomole of glycolipid could be detected. The procedure was used for analysis of human erythrocyte neutral glycolipids. |
