Freshly milled rice brain was extracted with hot 91 and 95% isopropanol to obtain the oil, sugars, and a considerable pootion of the B‐complex vitamins. After concentration of the micella a sugar‐syrup phase reparated from the oil. This syrup phase contained most of the extracted vitamins. Yields of oil and syrup were observed and vitamin assays made on the syrup and on the brain before and after extraction. The vitamins measured were biotin, folic acid, riboflavin, pantothenic acid, pyridoxine, thiamin, niacin, and inositol.
