Abstract
|
|
|
|
Water and ethanol extract of kernels and bran of Coix lacryma-jobi var. ma-yuen were prepared, and their antioxidant activities and effects on alcohol metabolizing enzyme activities were analyzed. Water extract of bran (BW) showed significantly higher phenolic contents, 1,1-diphenyl-2-picrylhydrazyl radical scavenging and 2,2’-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) radical scavenging activities. BW also greatly increased the alcohol dehydrogenase and acetaldehyde dehydrogenase activities. These results indicate that bran, which was a by-product generated during processing of C. lacryma-jobi var. ma-yuen, could be used to develop processed goods with several physiological activities.
