Teas of Equiseti herba, Myrtilli folium and Salviae folium

Equiseti herba, Myrtilli folium and Salviae folium drugs and teas were examined for metal ion-, sulfur-, phosphorus-, total polyphenol- and vitamin C content. Metal elements (Al, As, B, Ba, Ca, Cd, Co, Cr, Cu, Fe, K, Hg, Li, Mg, Mn, Mo, Na, Ni, Pb, Ti, V, Zn), sulfur and phosphorus of samples were determined by ICP-AES (inductively coupled plasma atomic emission spectrometry). Salviae folium proved to contain iron, magnesium and zinc in the highest level (956.8, 6075 and 33.26 mg kg -1 ). The teas contained dissolvable metal ions and polyphenols. The dissolution of calcium, magnesium, potassium and zinc was the highest from Equiseti herba (27.7, 46.6, 83.2 and 14.3%). The amount of polyphenol content was the higher in the drug (12.8%) and tea (3.6%) of Salviae folium. Myrtilli folium was found to contain extremely high amount of vitamin C (470 mg%).
