ABSTRACT
Objective To establish limit test method of camphor in Niuhuang qingxin pills (prescription of the bureau) . Methods The separation was performed on an HP-INNOWAX capillary column (0.25 mm×30 m, 0.25 μm) and the column temperature was 110 ℃ . The temperatures of the inlet and the FID detector were 200 and 230 ℃ , respectively. The flow rate of the carrier gas was 1.8 mL·min-1 and the split ratio was 10:1. The injection volume was 1 μL. Results Good linearity was obtained for camphor within the range of 1.65 to 165 μg·mL-1, and the average recovery of low, medium, high concentration were 99.12%, 99.56% and 99.56%, respectively,with RSD were 1.01%,0.69% and 0.38%, respectively. Trace camphor was found in 7 samples out of 38 samples from 9 manufactures. Conclusion The proposed method was accurate, sensitive and simple, and was suitable for quality evaluation and safety control of Niuhuang qingxin pills (prescription of the bureau) .
