K. Szentmihalyi et al., POTASSIUM-SODIUM RATIO FOR THE CHARACTERIZATION OF MEDICINAL PLANT-EXTRACTS WITH DIURETIC ACTIVITY, PTR. Phytotherapy research, 12(3), 1998, pp. 163-166
Atomic emission spectrometry was applied for the determination of pota
ssium and sodium concentrations in crude drugs and decoctions. The con
tent of the two elements and potassium-sodium ratios of medicinal plan
t extracts were measure as a basis for evaluating diuretic activity. T
he potassium-sodium ratios were higher in the diuretic plant decoction
s, than in crude drug decoctions used for different activities. (C) 19
