title: Antioxidant and electrochemical properties of calcium and lithium ascorbates.
abstract: The calcium and lithium pharmaceutical products have been widely used in medicine, especially at diseases of the mind. Bioactivity and toxically of novel complex ascorbates of calcium and lithium were considered in this work. Study of antioxidant properties of new forms of the compounds was carried out by differential pulse voltammetry. Cyclic voltammetry was used for investigation of their electrochemical properties in order to obtain information about electron-transfer reactions. The influence of these substances on the electrochemical oxygen reduction and its kinetic was also studied. As a result, the kinetic parameters interaction between reactive oxygen species and ascorbates of calcium and lithium were evaluated.
