Abstract

High-performance liquid chromatography with microparticulate silica gel and octadecyl silica reversed-phase columns accords ready resolution of the common autoxidation products of cholesterol. Resolution of two pairs of isomeric sterols (5,6α-epoxy-5α-cholestan-3β-ol and 5,6β-epoxy-5β-cholestan-3β-ol, 3β-hydroxy-5α-cholest-6-ene-5-hydroperoxide and 3β-hydroxycholest-5-ene-7α-hydroperoxide) not previously resolved chromatographically has been achieved in both systems. Application of the procedure to the isolation of cholesta-4,6-dien-3-one from autoxidized cholesterol is described.
