| Abstract: | The aim of this work is to establish a simple method to determination of metal elements in Gardneria multiflora Makino.The samples were digested by Microwave-digestion,and the metal ions（Ca,Cu,Fe,Zn,Pb） in digested samples were determined by Atomic Absorption Spectrometry.The results showed that the detection limits were below 0.0022 μg/mL,the relative standard deviations were less than 6.47%,and the addition standard recoveries were in the range of 92.2%-110.0%.The determination result are satisfied. |
