Abstract
The unsaponifiable matter of butterfat, castor oil, cocoa butter fat, corn, cottonseed, linseed, milo maize, peanut, rice bran, safflower, soybean, and tung oils was fractionated on a Florisil column and the third fraction (tocopherols, high molecular weight alcohols, and triterpenoid alcohols) was gas chromatographed. This fraction showed three homologous series, tentatively identified as normal, iso- and/or anteiso-, and multiple branched chain alcohols. Each sample was examined before and after hydrogenation with Adams catalyst. Gas chromatograms from most of the oils displayed characteristic patterns which could be used to identify individual oils.Keywords
