متن کاملTocopherols (vitamin E) in milk: their chemical determination and occurrence in human milk.
The method of Quaife and Harris (1,Z) for the estimation of vitamin E in blood plasma has been adapted to the determination of total tocopherols in milk. The quantities of milk, ethanol, and purified Skellysolve B (S&J used in the extraction mixture are increased proportionately as needed. For cow’s milk the increase is 6-fold. An aliquot of the SSr, layer (e.g., fivesixths of the total) is eva...
