Abstract
The analysis of sebum alcoholic mixtures directly by the gas chromatograph is beset by several difficulties such as the overlapping of some of the branched chain peaks, among others. As inherent with most mixtures of biological origin, the resolution or preparation of samples becomes a problem of prime importance. Accordingly, the alcohols obtained on saponification of hair lipids followed by chromatography of the unsaponifiable portion over alumina have been submitted to thin-layer chromatography (TLC) and each of the resulting fractions analyzed by temperature programmed gas chromatography. In this way, a variety of component peaks was afforded for further structural elucidation. Previously, a direct analysis of the alcohol and sterol mixture from hair lipids by gas chromatography without recourse to TLC was advanced by this laboratory (1).
