Abstract
IN the course of work on the oxidation products of vitamin E, we have oxidized a number of samples of d-α-tocopherol and synthetic dl-α-tocopherol with alkaline potassium ferricyanide. In studying the products from these oxidations, the interesting observation was made that the oxidation product from d-α-tocopherol had a high optical rotation, [α]25D = + 31.5°, whereas that of dl-α-tocopherol had no detectable rotation. This difference provides a convenien+ method for distinguishing between the d- and the dl-forms.
