Purification and identification of ,y-Oryzanol from Rice Bran

摘要

Abstract: A physiological active factor - r-oryzanol in rice bran was studied.The r-oryzanol was separated and identified by thin layer chromatograghy(TLC),reverse-phase HPLC, semipreparative HPLC and electrospray ionization/massspectrometry(ESI/MS). Its individual components, cycloartenol ferulate and 24-methylene cycloartenol ferulate were obtained. An effective method to purify andseparate the r-oryzanol is provided. Which is useful for further research on thefuctional claracteristies of r-oryzanol and for the development of new rice branproducts.
