An improved gas-liquid chromatographic method for the determination of fecal neutral sterols
M Arca, A Montali, S Ciocca, F Angelico and A Cantafora
The analysis of fecal neutral sterols has been improved by use of a highly
selective gas-liquid chromatography column packed with SP-2401. This
chromatographic column allows separation of cholesterol and cholestanol and
delta 5-5 alpha plant sterol homologs without employing silver nitrate
thin-layer chromatography. Furthermore, there is no need to derivatize
neutral sterols before injection. The main fecal neutral sterols are well
resolved; retention times are reproducible; detector response is
reproducible, linear, and sensitive to 0.2 micrograms. This method,
successfully used for fecal samples, may be suggested as a routine method
for the clinical study of cholesterol metabolism.
