ABSTRACT
Objective A headspace-gas chromatography method was established for determination of methanol in Huox-iang Zhengqi Tincture. Methods Headspace-gas chromatography was performed on a HP-INNOWAX capillary col-umn, with nitrogen as carrier gas and FID as detector. The injector temperature was at 150℃ and the detector tempera-ture was at 200℃ , and temperature programming and split stream sampling were used. Results A good linearity was obtained within the designed range, the average recovery was 98.89 % with the RSD of 1.36 %, which met the correla-tive criterion of China Pharmacopoeia. Conclusion This method is proved to be accurate, and it has a good reproducibil-ity and can be used to determinate the residual methanol in Huoxiang Zhengqi Tincture.
