Abstract: Copper-Salicylate complex was synthesized and its ability that inhibits the reduc-tion of NBT by the superoxide radical(O2·-) was measured in aqueous solution and in AOT, TX-100, CTAB lamellar liquid crystals systems. It is obtained that the copper complex had SOD-like activity either in solution(ID 50=1.1×10-6mol/L) or in AOT lamellar liquid crystal(ID50=2.0×10-5mol/L). Experiments show that AOT lamellar liquid crystal had SOD-like activity itself. The synergism of copper complex and AOT lamellar liquid crystal can enhance the SOD-like activity of the system.

Key words: Lamellar liquid crystals, Cu(Ⅱ)complex, SOD-like activity
