reaction product of nitric oxide and superoxide anion, and a powerful oxidant, was found to nitrate as well as oxidize adenine, guanine, and xanthine nucleosides. A highly sensitive reverse-phase HPLC method with a dual-mode electrochemical detector, which reduces the nitro product at the first electrode and detects the reduced product by oxidation at the second electrode, was applied to detect femtomole
