| Abstract: | On the basis of the previous results,response surface design is adopted by the Design-expert software according to the central composite design principle for studying the extracting condition of SOD in sweet potato leaves.The optimal extracting conditions are: beating time 2.4 min and liquid-to-solid ratio 3.6∶1 and pH 8.0.Under these conditions,the yield of SOD is 332.64 U/g and the model prediction is 350.24 U/g,so the error is 5.03%. |
