Sterol synthesis. High-pressure liquid chromatography of C27 sterol precursors of cholesterol
JR Thowsen and GJ Schroepfer Jr
Conditions have been described which permit the rapid (approximately 3.5
hr) column chromatographic separation of the acetate derivatives of a
number of C27 sterol precursors of cholesterol differing only in the number
and position of double bonds in the sterol nucleus. On columns containing
muPorasil with hexane-benzene 9:1 as the eluting solvent, acetate
derivatives of the delta5, delta8(14), delta8, delta7, delta8,7, delta
8,14, and delta7,14 sterols were separated.
