Atomic emission spectometry was applied for the determination of potassium and sodium concentrations in crude drugs and decoctions. The content of the two elements and potassium-sodium ratios of medicinal plant extracts were measure as a basis for evaluating diuretic activity. The potassium-sodium ratios were higher in the diuretic plant decoctions, than in crude drug decoctions used for different activities.
