A twofold technique for determination of tocopherols and a gas liquid chromatography procedure for determination of sterols and steryl esters are described. Incorporated herein are a modified Emmerie‐Engel procedure for total tocopherols and gas liquid chromatographic analysis for tocopherols and sterols as their propionate esters. The approach is directly applicable to quality control and production use.
