Distribution of tocopherols within the corn kernel
1970
Grams, G.W. | Blessin, C.W. | Inglett, G.E.
The concn. of tocols and tocotrienols in the germ, endosperm and pericarp of the corn kernel was determined after hand dissection of 4 dent corn hybirds - normal, early maturing, high oil and high lysine (opaque-2). Among these hydrids the germ fraction contained 70-86% and the endosperm fraction contained 27-11% of the tocopherols extracted from the whole grain. The endosperm fractions contain all of the measurable tocotrienols occurring in whole corn. In the 4 hybrids analysed, the germ fraction contained 94-96% of the α-tocopherol extracted from the whole grain. Concn. of α-tocopherol was the highest in the germ fraction of the opaque-2 hybrid.
