A method for the quantitative determination of cY-tocopherol in rat brain is described. The brain sample is homogenized in the presence of ascorbic acid, ethanol, and hexane. The hexane extract is analyzed directly using a liquid chromatograph which is constructed from parts available commercially.
The method described here is essentially a modification of the method of Dilley and Crane (1) but has the advantages of greater speed and simplicity and gives higher recoveries. ## MATERIALS Benzene, petroleum ether (S&80), diethyl ether, absolute ethanol, and acetone were all analytical reagent
