[Objective] To determine the trace elements in Hydrocotyle sibthorpioides Lam. of Kaili. [Method] The contents of five trace elements including Zn, Fe, Cu, Mn and Se in Hydrocotyle sibthorpioides Lam. were determined by flame atomic absorption spectrometry (FAAS) and hydride generation atomic fluorescence spectrometry (HG-AFS). [Result] Different colors of Hydrocotyle sibthorpioides Lam. from Xiasi of Kaili were rich in Zn, Fe, Cu, Mn and Se which were essential to human body, the contents of five trace elements decreased according to the following order Fe>Mn>Zn>Cu>Se; and the contents of Zn, Cu, Fe and Mn in green Hydrocotyle sibthorpioides Lam. were almost twice that in red Hydrocotyle sibthorpioides Lam., Se contents in two samples differed insignificantly and the measured Se contents were all above 0.110 μg/g, therefore Hydrocotyle sibthorpioides Lam. belonged to high selenium plants. The recoveries and relative standard deviation (RSD) of these trace elements were among 98.1%-104.2% and 0.01%-2.22%, respectively. [Conclusion] This research provides scientific basis for evaluating the medical value of local Hydrocotyle sibthorpioides Lam.

The recoveries and relative standard deviation (RSD) of these trace elements were among 98.1% -10 4.2% and 0.01% -2.22%, respectively.
