摘要：
Modified glassy carbon electrode with carbon nanotubes (CNT/GCE) was used to study extracted saffron in blood medium to find the effect of oxidation-reduction current peaks of saffron compound. It was found two cathodic current peaks at -0.75 and -1.75 V were appeared in the cyclic voltammogram of saffron in blood medium, so saffron considered as anti-oxidative compound in blood medium. Different concentrations, scan rates and effect of ascorbic acid on the cathodic current peak were studied. Diffusion coefficient of two reduction current peaks of saffron in blood medium was determined from Randel equations with values of saffron in blood medium at -0.75 and -1.75 V are 2.2x10(-6) and 1.1x10(-5) cm(2)/sec respectively cm(2) sec(-1).
