[Determination of 23 elements in lady's thistle (Silybum marianum L. Gaertner)].
23 elements (Al, As, B, Ba, Ca, Cd, Co, Cr, Cu, Fe, Hg, K, Li, Mg, Mn, Mo, Na, P, Pb, S, Ti, V, Zn) were measured in lady's thistle (Silybum marianum L.) herba and fructus by ICP-AES technique after digestion in teflon vessels. This is the first report about the content of these elements in the plant originated from Hungary. This measurements is important in view of plant physiology and pharmacology. Significant amounts of aluminium and iron were measured in lady's thistle herba. In the course of tea making, the relative concentration of some elements decreases because of the poor solubility of the compounds of these elements. The low concentration of these elements in teas in favourable in pharmacological aspect. No significant differences were found in boron, calcium, potassium and magnesium concentrations of lady's thistle fructus samples of different origin.
