Abstract:Tocopherols of oil palm leaves were determined by high perfor-mance liquid chomatography. Each tocopherol was identified by a combination of gas chromatography-mass spectrometry and thin layer chromatography. The extracts of the leaves contained α- tocopherol (11,229-14,805 μg/g) and β-tocopherol (30-44 μg/g). Tocopherol composition and content of the leaves was compared to those of oil palm fruits. Presented at the JOCS meeting, Tokyo, November 1982.
