| Abstract: |
| A method for determination of seven inorganic elements(Ca, Mg, Mn,Fe, Cu, Zn, and Sr) in Jinji Capsules has been developed. The sample was digested with the acid mixture of HNO3+HClO4 (8+2) and then was analyzed by inductively coupled plasma atomic emission spectrometry (ICP-AES). The results showed that there were many kinds of inorganic elements good to human being health in the Jinji capsules. These elements include Ca, Mg, Fe, Mn, Zn, Sr and Cu and their contents were determined as 16356, 8525,714.3, 234.7, 52.49, 34.69 and 2 0.70 μg/g, respectively. The recovery ratios for each element determined by standard addition method were in the range between 95.4% and 104.8%(n=3); and relative standard deviation (RSD) were in the range between 1.4% and 6.2% (n=6). It concluded that the method was simple and rapid, the results were accurate and reliable. It can be used for simultaneous determination of multiple elements in Chinese traditional patent medicine. |
