Components of the unsaponifiable matter of crude rice bran oil were examined. A new compound having melting point of 157~158°C was obtained. Molecular weight was determined and ultraviolet and infrared analyses were carried out. Squalene and ferulic acid ester were confirmed to exist in the unsaponifiablc matter of crude rice bran oil. Quantitative relation of components was calculated and found to be 42% sterols, 24% higher alcohols. 20% ferulic acid esters, 10% hydrocarbons and 2% unreported compound.
