摘要：

Antioxidative compounds were solubilized from an insoluble dietary fiber, refined corn bran (RCB), by enzymatic hydrolysis. Antioxidative activities (AOA) of 5-O-feruloyl-L-arabinofuranose (FA) and O-(5-O-feruloyl-alpha-L-arabinofuranosyl)-(1-->3)-O-beta-D-xylopyranosyl-(1-->4)-D-xylopyranose (FAXX) were slightly stronger than that of ferulic acid. AOA of high molecular fraction were stronger than those of ferulic acid, FA, and FAXX. Diferulic acid was an active constituent among the alkaline hydrolysate of high molecular fraction. AOA of ferulic acid sugar esters, FA, and FAXX were stronger than that of free ferulic acid in the microsomal lipid peroxidation system.
