英文摘要	The contents of twenty kinds of trace elements, Al, Ba, Ca, Co, Cr, Cu, Fe, K, Li, Mg, Mn, Mo, Na, Ni, P, Pb, S and Zn, were determined by ICP-MS with microwave digestion in Urtica laetevirens Maxim. The recovery(n=7) is 95.4%similar to 101.2%, and the RSD(n=7) is 1.2%similar to 5.3%. The contents of K, P, S, Ca and Na in the samples were abundant while Fe, Mg, Mn and Zn were less abundant. The contents of Al, Cr and Pb which were harmful to human were kept at low level. The contents of trace elements in Urtica laetevirens Maxim, also showed obvious seasonal dynamics. This result provides some theoretical basis for the study of internal relations between trace elements in Urtica laetevirens Maxim. and its efficacy. It's also useful for better development and utilization of the resource.
