[摘要]
目的:采用高效液相法对尼群地平片进行含量测定。方法: 色谱柱为Diamonsil( TM) - C18 ( 250 mm
× 4. 6 mm,5μm) ,流动相为甲醇-水( 70: 30) ,检测波长为237nm,流速为1. 0 mL/min,进样量为10μL。结果: 在
此条件下,尼群地平进样量在0 ~ 2. 5μg 范围内线性关系良好( R2 = 0. 9996) ,平均回收率为100. 18% ( n = 9) 。
结论:本方法简便、准确、快捷,重复性良好,可用于尼群地平片剂的含量测定和质量控制。

Objective: Use HPLC method to determine the content of Nitrendipine Tablets. Methods:
The Diamonsil( TM) - C18 column( 250 mm × 4. 6 mm,5 μm) was used with the mobile phase of
methanol - water( 70: 30) , the detection wavelength was 237nm, the flow rate was 1. 0 mL /min, the injected
quantity was 10μL. Results: Under these conditions, the linear relationship was good when the
injected quantity of Nitrendipine was in the range of 0 ~ 2. 5μg( R2 = 0. 9996) , the average recovery
rate of this method was 100. 18% ( n = 9) . Conclusion: This method is convenient,accurate, rapid,
good epeatability,and suitable for determining the content of Nitrendipine tablets and quality control.
