The chromatographic patterns of prostaglandin E2 chromatographed on various lots of silicic acid are presented. Two lots of Mallinckrodt silicic acid tested give totally unsatisfactory separation of PGE2. Sigma silicic acid SIL-R gives better separation than any of the Mallinckrodt lots tested. Increasing the size of the "E" fraction of solvent can give satisfactory separation on Mallinckrodt silicic acid.
文中呈现了前列腺素E2在不同批次硅酸上的色谱图。测试的两批马林克罗特硅酸对PGE2的分离效果完全不理想。西格玛硅酸SIL-R的分离效果比测试的任何一批马林克罗特硅酸都要好。增大溶剂中“E”部分的量能在马林克罗特硅酸上实现令人满意的分离。
