Abstract：The contents of K, Ca, Na, Mg, Fe, Cu and so on in the roots of Paeonia lactiflora Pall and in the soil in which they grew were determined by ICP-AES technique to study the mineral elements utilization of P. lactiflora Pall. The results indicate that the elements utilization rate of P. lactiflora Pall is different in different locations, so the contents of mineral elements in the roots of P. lactiflora Pall and even the quality of medicinal materials coming from them in different locations are different. The contents of Ca，Fe，Zn and so on in Chi Shao in Heilongjiang and Inner Mongolia are relatively high. The contents of mineral elements in soil influence not only themselves’ utilization but also other mineral elements utilization of P. lactiflora Pall.
Key words：ICP-AES;Paeonia lactiflora Pall;Mineral element
