Rezumat: Antioxidants plays one of the main role in protection of normal vital functions of organisms. The main sources of natural antioxidant are plant extracts. Because of antioxidants are reducers, they have strongly activity with oxygen and intermediates of oxidizing of organic compounds. Decreasing of yield of antioxidants, nonreproductivity of concentrations, problems with storage are technical effect of high activity of antioxidants. It is known that stability of reducers in the solid phase in comparison with those in the liquid phase is strongly higher. We showed availability of using of solid phase mechanochemical reaction for producing of preparations of unstable antioxidant compounds from plant material. The ratio of oxidizing of active component – green tea catechins and naphtodiantrones from St. John’s Wort in the solid mechanochemical preparation in comparison with those in liquid preparation was decreased not less than 500 times. The yield of active components increased in 2-10 times.
