中文摘要superoxide anion radical (o-2 radical anion) plays an important role in several human diseases. the xanthine/xanthine oxidase system is frequently utilized to produce o-2 radical anion. however, false positive results are easily got by using this system. the common spectrophotometric probes for o-2 radical anion are nitroblue tetrazolium (nbt) and cytochrome c. nevertheless, the application of nbt method is limited because of the water-insolubility of nbt formazan and the assay using cytochrome c lacks sensitivity and is not suitable for microplate measurement. we overcome these problems by using 1,2,3-trihydroxybenzene (pyrogallol) as o-2 radical anion-generating system and a highly water-soluble tetrazolium salt, 2-(4-iodophenyl)-3-(4-nitrophenyl)-5-(2,4-disulfophenyl)-2h-tetrazolium sodium salt (wst-1) which can be reduced by superoxide anion radical to a stable water-soluble formazan with a high absorbance at 450 nm. the method is simple, rapid and sensitive. moreover, it can be adapted to microplate format. in this study, the o-2 radical anion scavenging activities of superoxide dismutase (sod), l-ascorbic acid, n-acetyl-l-cysteine (nac), albumin from human serum, flavonoids and herbal extracts were assessed by using this method. meanwhile, the activities of tissue homogenates and serum were determined by using this validated method. this method, applicable to tissue homogenates, serum and herbal extracts, proved to be efficient for measuring o-2 radical anion scavenging activities of biological and abiological samples.
