ORYZANOL
|
Resumen:
|
The oryzanol content of rice bran oil samples ranged from 1.1-2,6 % The soap stock obtained by alkali refining of the oil contained 1.3-3.1% oryzanol. The optimum pH for extraction of oryzanol from soap stock was around 9.5 and diethyl ether was the best solvent. The oryzanol concentrate could be further upgraded by alumina column chromatography and recrystallized using methanol and methanol-acetone (2:1). The recrystallized material (98% pure) had a melting point of 133-139 ºC and absorption maxima at 314, 290 and 230 nm in petroleum ether.
