| 摘 要： | 刺梨中的SOD活性在40－60℃的温度下比较稳定，酶活力至少保存60％；SOD活性在PH值6-8左右时相对稳定，PH＞8．0或PH＜6．0后酶活力迅速丧失；高浓度的Cn2+和Zn2+对SOD活性有抑制作用，2－6mmol/L的Zn2+对SOD活性有稳定效果，SOD保存在表面活性剂吐温—20中较好．

| Abstract: | The temperature SOD activity in barbed pear was steady and retained 60% at lest was 40-60℃ .The PH that SOD ectivity was relatitely steady was about 6-8, PH＞ 8 or PH＜6, SOD activity was lost xapidy.High concentration Cu2+ and Zn2+ restrain SOD activity, The concentration that can steady SOD activity was 2-6 m mol/L That SOD was retained in Tween-20 solution was better. |
