A quantitative determination of tocotrienols and tocopherols in palm oil by TLC-GLC

A reliable analytical method is required for determining tocopherols and tocotrienols in palm oil and palm oil fractions. This paper describes a TLC/GLC method which distinguishes between these compounds and is based on their separations from palm oils by saponification and TLC, followed by direct GLC analysis.
