Alpha-tocopherol in vegetable oils. 1980

S Changbumrung, and T Buavatana, and P Migasena

The alpha-tocopherol concentration was determined in cooking vegetable oils. The lowest concentration of alpha-tocopherol was found in coconut oil. Soybean oil, peanut oil and rice bran oil showed similar ranges of alpha-tocopherol concentration. A high concentration of alpha-tocopherol was found in palm oil and in corn oil. The combination of single vegetables oils affected the alpha-tocopherol concentration as shown in the samples of mixed oils. The ratio of alpha-tocopherol to polyunsaturated fatty acids has been calculated.

UI MeSH Term Description Entries
D009821 Oils Unctuous combustible substances that are liquid or easily liquefiable on warming, and are soluble in ether but insoluble in water. Such substances, depending on their origin, are classified as animal, mineral, or vegetable oils. Depending on their behavior on heating, they are volatile or fixed. (Dorland, 28th ed)
D014675 Vegetables A food group comprised of EDIBLE PLANTS or their parts. Vegetable
D014810 Vitamin E A generic descriptor for all TOCOPHEROLS and TOCOTRIENOLS that exhibit ALPHA-TOCOPHEROL activity. By virtue of the phenolic hydrogen on the 2H-1-benzopyran-6-ol nucleus, these compounds exhibit varying degree of antioxidant activity, depending on the site and number of methyl groups and the type of ISOPRENOIDS.
