摘要
目的:测定消喘膏中延胡索乙素的含量。方法:色谱柱为Dikma Diamonsil C18(200mm×4.6mm,5μm),流动相为甲醇-0.1%磷酸溶液(三乙胺调pH值至6.0)(55:45),流速为1.0ml·min-1,检测波长为280nm。结果:延胡索乙素进样量在0.051μg-1.020μg范围内与峰面积呈良好的线性关系(r=0.9999),平均回收率为99.35%(n=9).RSD为0.75%。结论:本方法简便快速,分离度好,结果准确可靠。
Objective. To determine tetrahydropalmatine in Xiaochuan Gao by HPLC. Methods: HPLC column was Dikma Diarnonsil C18 ( 200mm × 4.6mm, 5μm), mobile phase was Methanol - 0.1% phosphoric acid solution( triethylamine adjusted pH to 6.0)( 55: 45), flow rate was 1.0mL·min^-1 and detection wavelength was 280nm. Results: The calibration curve was linear in the range of 0. 051μg--1. 020μg for tetrahydropalrnatine( r=0. 9999), The average recovery was 99. 35 % and RSD 0.75 % (n = 9). Conclusion. The method with good separation is convenient, rapid, accurate and reliable.
