目的 :测定洛斯宝活血素口服液中二氢麦角隐亭 (甲磺酰盐 )和咖啡因的含量。方法 :在ODS柱上 ,以0 0 5mol·L 1 KH2 PO4溶液 (pH2 5) 乙腈 (5 4)为流动相 ,紫外检测波长 2 2 3nm。 结果 :二氢麦角隐亭的平均回收率为 99 94% ,RSD为 0 1 7% ,咖啡因的平均回收率为 1 0 0 34 % ,RSD为 0 2 5 %。结论 :该法简单快捷
OBJECTIVE: To determine the contents of dihydroergocryptine (methanesulfonate) and caffeine in losartan huoxuetong oral solution. Methods: The mobile phase was acetonitrile (5 4) with 0 0 5 mol·L -1 KH 2 PO 4 solution (pH 2 5) as mobile phase on ODS column. The UV detection wavelength was 2223 nm. RESULTS: The average recovery of dihydroergocryptine was 99.94% with a RSD of 0 1 7%. The average recovery of caffeine was 10034% with a RSD of 0 2 5%. Conclusion: The method is simple and quick
