A component of rice bran oil is the γ-oryzanol, at around 2% of crude oil content. Thought to be a single compound when initially isolated, γ-oryzanol is now known to be a mixture of steryl and other triterpenyl esters of ferulic acids. Also present are tocopherols and tocotrienols (two types of vitamin E) and phytosterols. ;Fatty acid composition ;Physical properties of crude and refined rice bran oil
