Chromatographic Separation of Allylic Alcohols on Silicic Acid Columns: Analysis of the Nonsaponifiable Lipids of an Ascites Tumor Derived from a Benzpyrene-induced Sarcoma.

s i l i c i c acid column chromatography has proved very useful in the separation and isolation of many of the sterols found in the nonsaponifiable fraction of lipid mixtures (1-8). In the course of an investigation of the nonsaponifiable lipids formed from mevalonic acid-C14 by a rat ascites tumor, a highly radioactive fraction was isolated by chromatography 011 silicic acid. This fraction was shown to contain a large amount of radioactive trans-trans-farnesol. This finding stimulated an investigation of the chromatographic behavior of some other allylic alcohols on silicic acid columns.
