Abstract:
OBJECTIVE: To establish a CGC method for the determination of pyridine in Potassium Dehydroandrograpol-ide Succinate. METHODS: The determination was performed on HP-INNOWAX capillary with column temperature at 100℃. The FID detector was used and the carrier gas was nitrogen. RESULTS:The linear range of Pyridine was 2.46～39.3?g?mL-1 and the average recovery was 98.07%,RSD=4.00(n=9).Its detection limit was 0.2?g?mL-1.CONCLUSION: The method is accurate and rapid, and applicable for the determination of the residual level of Pyridine in Potassium dehydroandrograpolide succinate.
