Concentrations of (137)Cs and (40)K in different tissues of edible wild herbaceous plants, that is, leaf blade and petiole for giant butterbur (Petasites japonicas (Siebold et Zucc.) Maxim.), and leaf, stem and strobilus for fertile shoot of field horsetail (Equisetum arvense L.) were measured in
The flavonoid fractions of Solidago virgaurea L.S. gigantea Ait., S. canadensis var. canadensis and S. canadensis var. "scabra" flowers were administrated p.o. to rats and showed diuretic activity. Increase in overnight diuresis reached 57-88%. Decrease of overnight excretion of potassium and sodium
