| Abstract: | Objective： To explore microwave digestion / inductively coupled plasma emission spec- troscopy （ICP-AES） determination of trace elements in China Tinospora content. Methods,Determined 8 trace elements including cobalt, chromium, copper, manganese, nickel and so on in Chinese Tinospora cadmium with microwave digestion and ICP-AES determination. Results, Under the best working condi- tion, each element recovery rate of each element was 90.0~104.0%, with the relative standard deviation （RSD） as 0.9%-1.9% and detection limit as 1-8 ng / L. Conclusion： This method is fast and con- venient, with high accuracy. It is satisfactory in determination of trace elements in Chinese herbal medicine. |
