In order to explore the best conditions of hordeumin extraction,According to the results of single factor experiment to choose test level,This experiment adopts the Plackett-Burman method to determine which is the major factor influencing the extraction of hordeumin,identified the optimization of extraction conditions of hordeumin from barley bran by response surface analysis. The best conditions:fermentation time of 7days,generating temperature 32℃,pH 4.0 ,under these conditions, the yield of hordeumin was 0.724 mg/g.
