[Free and bound sterol content of sunflower, soy bean and maize oils].

The amounts of free sterols, steryl esters and steryl glycosides in sunflower, soya and maize oils as well as in the phosphatides of the same oils were determined. The refinement byproducts were enriched with sterols. The highest contents of total sterols and steryl glycosides (2,68 and 1,9%, respectively) were established in soya phosphatides followed by those in sunflower oil phosphatides (2,03 and 1,68%, respectively) and maize oil phosphatides (0,81 and 0,54%, respectively).
