abstract：:A simple, sensitive, and accurate method for determination of cholestanol in plasma is described. In this method a fixed amount of cholestane is added to 1 ml of plasma as an internal standard and steroids are saponified and extracted with n-hexane. The amounts of cholestanol and cholesterol are determined by mass fra...
