摘　　要：通过考察抽提野生菊芋SOD的温度,pH和体积并进行优化,探讨菊芋SOD的最佳提取工艺。结果表明:提取温度40℃,时间20 min,pH 6,丙酮︰酶液体积比为3︰1,菊芋SOD能够达到相对最大酶性。Studied the technological process of the SOD from wild Helianthus tuberosus.Compared the experimental results obtained by different treatment,including heat treatment,isoelectric fraction,acetone fractionation and orthogonal experiment.The best process was as follows： extracting temperature 40 ℃;extracting pH 6;extracting time 20 min;the volume of inulinase and acetone is 3︰1,which provided experiment basis for extracting SOD from Helianthus tuberosus in mass industry.
