Abstract
Using anhydrous ethanol as extracting solvent,the technique of ultrasonic assisted extraction of black rice anthocyanins and its antioxidation were investigated.The results showed that the optimum extraction codition were temperature 50℃,ethanol volume fraction 35%,feed liquid ratio of 1:4,extracting time for 30 min.And comparison with no ultrasonic assisted extraction,ultrasonic assisted extraction black rice anthocyanins when ultrasonic power is 90 W,ultrasonic extraction time is 4 min,its antioxidation is the largest,so the ultrasonic assisted extraction black rice anthocyanins is a kind of effective method.
