Abstract: Anew Schiff base, 2-hydroxy-1-napthaldehyde-2-amino thiazole(HNATS) and its Cu(Ⅱ) complex was synthesized. The complex[Cu(Ⅱ)-(HNATS)2] could exhibit an efficient peroxitase like catalytic activity, and catalyze the coupling reaction of 2,4-dichlorophenol and 4-amino antipyrine with hydrogen peroxide. The effect of SDSon the catalytic activity of mimetic enzyme was studied. Based on the reaction, the determination of O2·- by this new spectrophotometric method was developed. The proposed method was used to determine SODactivity of garlic, scallion and onion with satisfactory results.

Key words: Surfactant, Mimetic enzyme, Catalytic spectrophotometry, Superoxide anion radical, Superoxide dismutase
