Brassia family have an indole methyl glucosinolate named “Glucobrassecin”. One of degradation products of this glucosinolate is indole- 3- carbinole (13C) which has anticarcinogenic properties. Degradation of glucosinolates is caused by hydrolytic effect of mirosinase enzyme released by damaged plant cell. Most of the studies about the anticancer properties of 13C were done with animal studies.According to brassica tissica properties and existence of high amont of ascorbic acid (AA), 13C combinr with AA and produce ascorbigen an anticarcinogenic compound and as a source of AA. In this study, we used from the relationship of 13C to AA for measurement of 13C by Voltammetric method. For this pupose, voltammograms of ascorbic acid in citrate phosphate buffer with optimum pH = 3.2 and sweep rate of 7500 mv/s and concentrations of 1- 175 μg/ml were drawn and then under this condition, different concentrations of 13C were added to the highest concentration of ascorbic acid. Analysis of the result showed that curve of the curve of 13C with different concentrations versus current was logarithmic. Detection limit of 13C was 0.001 mM. Relative standard deviation of method repeatability for concentrations of 0.8 mM, 0.5 mM and 0.15 mM were 5.2%, 5% and 5.6% respectively. Curve of concentration against logarithm of current was linear and also sensitivity of method was – 2.65 log A/mM.
