| Abstract: | The determination of the mineral elements in Populus yunnanensis Dode was investigated by ICP-OES with microwave digestion.The RSD for the method was 0.5%—3.8%,and the recovery was 96.7%—104.4%,that indicated the satisfactory accuracy and precision of this method.The eleven mineral elements in Populus yunnanensis Dode,including Ca,Mg,Fe,Zn,K,Mn,P,B,Cu,Na and Si,were determined by the method.The content of Cu was significantly lower than the level required for the growth of this plant,while the otier ten elements were sufficient for normal growth. |
