|Title:||Fatty Acid And Vitamin E Content Of Nutrimaiz, A Sugary /opaque-2 Corn Cultivar|
Strong III F.C.
Da Silva W.J.
|Abstract:||Comparative analyses were carried out on Nutrimaiz (a corn cultivar with Sugary/Opaque-2 endosperm), derived from Opaque-2 and Sugary varieties, on its progenitors, and on a common corn (Maya XII Normal) for tocopherols, tocotrienols, and fatty acids. A shorter procedure was developed for extracting nonsaponifiable material (containing the tocols) after direct saponification of the sample, instead of first extracting the lipids. Individual tocopherols and tocotrienols were separated by TLC on silica gel, extracted, and determined by a new reaction with cupric ion and a complexing agent, either cuproine or bathocuproine. Fatty acids were determined by GLC of their methyl esters. Nutrimaiz was found to be more similar to Sugary than to Opaque-2 in total lipids, fatty acids, and total tocols, indicating that the Sugary gene is epistatic over that of Opaque-2 for these traits. Results expressed on a dry basis showed that all varieties increased in total lipids and total tocols in going from the fresh to the mature state. © 1982 American Chemical Society.|
