摘　　要：本文研究了阴离子Ｃ１２Ｈ２５ＳＯ４Ｎａ（Ｃ１２Ｓ），Ｃ１２Ｈ２５（ＯＣ２Ｈ４）７ＳＯ４Ｎａ（Ｃ１２Ｅ７Ｓ），阳离子Ｃ１２Ｈ２５ＮＣ（ＣＨ３）３·Ｂｒ（Ｃ１２ＮＭｅ３）和非离子Ｃ８Ｈ１７Ｃ６Ｈ４（ＯＣ２Ｈ４）１０ＯＨ（Ｔｘ－１００）表面活性剂对超氧化物歧化酶（ＳＯＤ）活力的影响以及变性后的复性。结果表明，Ｃ１２Ｅ７Ｓ和Ｔｘ－１００对ＳＯＤ的活力几乎无破坏，Ｃ１２Ｓ对ＳＯＤ只具有一定的破坏性。The effect of anionic (C 12 H 25 SO 4Na, C 12 S,C 12 H 25 (OC 2H 4) 7SO 4Na, C 12 E 7S, Cationic (C 12 H 25 NC(CH 3) 3·Br(C 12 NMe 3) and nonionic (C 8H 17 ·C 6H 4·(OC 2H 4) 10 OH, (Tx-100) surfactants on the activity of superoxidized dismutase (SOD) and the renaturation of denatured protein have been studied. The results indicate that there are almost no effects of C 12 E 7S and Tx-100 on the activity of SOD and the effect of C 12 S on the activity of SOD is much smaller than that of C 12 NMe 3.
