Objective

To establish a method for the simultaneous determination of trace elements in Pyrus sinkiangensis Yu and Qiuli lung moistening paste by pressure tank digestion and inductively coupled plasma mass spectrometry (ICP-MS).

Methods

The samples were digested in a pressure tank at 80 ℃ for 2 h, 120 ℃ for 2 h and 165 ℃ for 4 h, and then analyzed by ICP-MS. The accuracy and reliability of the method were evaluated through methodological studies.

Results

The linear relationship of each element was good within a certain range (r>0.9996)based on the results of the methodological studies. The relative standard deviations (RSDs) of precision were 0.03% to 8.32%, indicating good instrument precision. The RSDs of repeatability were 0.03% to 3.17%, indicating good repeatability. Both Pyrus sinkiangensis Yu and Qiuli lung moistening paste contained 16 kinds of trace elements including beryllium, boron, titanium, vanadium, chromium, manganese, cobalt, nickel, copper, zinc, gallium, arsenic, strontium, cadmium, barium and lead. Pyrus sinkiangensis Yu contained more lithium than Qiuli lung moistening paste. The content of 8 kinds of elements including titanium, vanadium, chromium, manganese, cobalt, nickel, zinc and cadmium in Qiuli lung moistening paste made from Pyrus sinkiangensis Yu was higher than those in the main raw material.

Conclusion

This method requires a small sample size, has a low limit of detection, high sensitivity and accuracy, and can be used for the simultaneous determination of multiple Pyrus sinkiangensis Yu.
