目的建立伤痛宁胶囊中延胡素乙素的含量测定方法。方法采用高效液相色谱法测定,Dikma Diamonsil C18柱,以甲醇-0.1%磷酸(55 45)为流动相,流速1.0ml/min,柱温:30℃,检测波长:280nm。结果延胡素乙素的线性范围为0.1150-0.6900μg;平均回收率为99.74%,RSD为0.7%(n=9)。结论所用方法测定样品灵敏度高,重复性好,可用于伤痛宁胶囊的质量控制。
Objective To establish a method for the determination of Penehyclidine B in Tongtongning capsule. Methods The mobile phase was Dikma Diamonsil C18 column with methanol-0.1% phosphoric acid (55 45) as mobile phase at a flow rate of 1.0 ml / min. The column temperature was 30 ℃ and the detection wavelength was 280 nm. Results The linear range of fevanin B was 0.1150-0.6900μg. The average recovery was 99.74% with a RSD of 0.7% (n = 9). Conclusion The method used in the determination of samples with high sensitivity and reproducibility, and can be used for the quality control of Tongtongning capsule.
