Determination of the Contents of Rare Earth Elements in Different Tissues of Pyracantha fortuneana

Purpose:Determined the contents of rare earth elements in the leaves and fruits of Pyracantha fortuneana. Method:Established the ICP-MS Analysis Sc, Y, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb and Lu 16 kinds of rare earth elements in Pyracantha fortuneana at the same time. And compared the contents of rare earth elements in the two tissues. Results:The method was simple, fast and reliable, good linear relationship, the coefficient of determination R² was higher than 0.9991, detection limit was less than 0.5 μg·kg^-1. The relative standard deviation of the precision experiment was between 0.5%~3.2%. The results of Huangqi standard substance were all within the recommended range. Conclusion:The leaves and fruits of both had high rare earth elements. Pyracantha fortuneana, and the leaves (592 μg·kg^-1) was much higher than fruits (104 μg·kg^-1).
