Objective: To determine the content of Arsenic(As)in radix notoginseng
panaxatriol saponins(PTS)and Sanqi Tongshu capsule. Method: The content of As was determined by hydride generation atomic fluorescence spectrometry. The optimal experimental conditions of microwave digestion-hydride generation were optimized. Result: Fluorescence intensity and concentration was in a good linear relationship;the linear range was 0-12 ng·mL-1and the recovery was in the range of 88.37%-104.76%
the detection limit was 0.109 6 ng·mL-1
RSD 0.82%;the content of As in PTS and its preparation were low. Conclusion: The method was simple
rapid and high sensitive. It can be used in the determination of As in radix notoginseng
