Methods are given for determining individual tocopherols in natural oils and food‐stuffs. These methods consist of either a single‐dimensional separation on zinc carbonate‐impregnated paper, or this separation in conjunction with a second‐dimensional partition separation on paraffin‐coated paper. Chromatographic runs are short and rapid and can be made without preliminary removal of carotenoids and moderate amounts of vitamin A or sterols. Over 98% recoveries are obtained with pure tocopherols. The presence of the recently described 5‐methyltocol in wheat products has been confirmed, and, in addition, using two‐dimensional methods, a substance has been isolated from some cereal grains, which appears to be a new tocopherol.
