Abstract
AbstractTotal and free sterols were measured by a modified Sperry‐Webb procedure in raw and refined corn, cottonseed, safflower seed, linseed, soybean and wheat germ oils. Wheat germ and safflower seed oil sterols were relatively rich in fastreacting sterols, which predominated in the sterol ester fraction. Photometric constants following color reaction were obtained for cholesterol and plant sterols and applied to a procedure for analysis of cholesterol and plant sterols in mixtures thereof.
