Ecologo-Biochemical Specific Features of Accumulation of Biologocally Active Substances in Some Species of Geraniaceae n the South Urals

V.S. Nikitina, O.E. Orazov, G.V. Shendel

Abstract

The levels of accumulation of phenolic compounds and flavonoids, as well as variability of biochemical composition in the air part of four Geranium L. species from different soil-ecologic areas of the South Urals were determined. The dynamics of accumulation of phenolic compounds and flavonoids in air parts of Geranium pratense, G. sylvaticum and G. sanguineum according to stage of vegetation was studied. The ecotypes of Geranium with high flavonoids content were determined, which are promising for isolation of biologically active substances exhibiting antiviral and antioxidant action.
