Determination of the Contents of Trace Elements in Arundina graminifolia (D.Don) Hochr.

摘要(Abstract):

[Objective] The aim was to establish an easy and rapid method to determine the content of five trace elements in Arundina graminifolia (D.Don)Hochr.. [Method] The contents and dissolution rates of Ca, Cu, Fe, Pd and Zn in A. graminifolia were determined by flame atomic adsorption spectrometry after normal digestion. [Result] A. graminifolia had abundant contents of Ca, Fe and Zn, which were 919.80, 361.10 and 39.89 μg/g, respectively; but the dissolution rates of Ca and Fe from the decoction were very low after water boiling. [Conclusion] The digestion method with platen heater had the advantages of simple equipment, convenient operation, complete digestion, high precision, and good accuracy. Therefore, it was one of the best methods to determine the trace elements.
