Determination of Contents of Trace Elements in RADIX PUERARIAE THOMSONII

[Objective] To determine the contents of trace elements in RADIX PUERARIAE THOMSONII. [Method] Flame atomic absorption spectrometry (FAAS) method was adopted to determine the contents of 4 trace elements including Mg, Fe, Mn and Zn in 7 kinds of RADIX PUERARIAE THOMSONII. [Results] RADIX PUERARIAE THOMSONII was rich in Mg, Fe, Mn and Zn; contents of trace elements were various not only in different producing areas and species, but also in different species from the same producing area. [Conclusion] This research could provide reference for further exploitation and utilization of RADIX PUERARIAE THOMSONII resource.
