Resveratrol was extracted from wine mud by alcohol precipitation method with the assistance of enzymoly?sis,and optimum extraction was explored. The effects of enzyme concentration,enzymatic hydrolysis temperature, and time on the yields of resveratrol were studied by single factor and orthogonal array design methods. The result is that enzyme concentration and hydrolysis time have a significant impact on the effectiveness of resveratrol extract , and the optimum extraction conditions are as follows:pH value 4.0,enzyme concentration 1.5mg/g,enzymatic hydro?lysis temperature 40℃and hydrolysis time 75min. Under such conditions,the yield of resveratrol is 80.2μg/g.
