Impact of low ionized plasma UVC radiation of air spark discharge on amino acids and nitrogenous bases was investigated. Primary active species produced under low ionized pulse plasma radiation are radicals HO2·, O· and N2O. Secondary active species are HNO2, HNO3, ONOO- and ONOOH. If primary active species are at once interacted with substrate molecules, peroxynitrite and peroxynitrous acid don't produce. It was stated that amine and carboxylic acid functional groups of amino acids don't damage by pulsed plasma radiation, side-chain radical of amino acids can be oxidized or reduced. As result low molecular products: ketones and aldehides are appeared and accumulated. Breakup of bonds C-N and C-O take place in nitrogenous bases. In course of this process the ketones and aldehides also are produced. Carbonyl group (C=O) of ketones and aldehides don't destroyed under low ionized pulse plasma radiation, therefore ketones and aldehides are final products of destruction.
