【摘要】：目的:建立測定氫溴酸山莨菪堿片的含量和含量均勻度的方法。方法:采用高效液相色譜法。色譜柱為Sun Fire C8,流動(dòng)相為乙腈-0.1%庚烷磺酸鈉溶液(用磷酸調(diào)節(jié)p H值至2.5)(40∶60,V/V),流速為1.0 ml/min,柱溫為28℃,檢測波長為256 nm,進(jìn)樣量為10μl。結(jié)果:氫溴酸山莨菪堿的質(zhì)量濃度在2.5~100μg/ml范圍內(nèi)與峰面積呈良好的線性關(guān)系(r=0.999 9);精密度、重復(fù)性、穩(wěn)定性試驗(yàn)的RSD1%;平均加樣回收率為99.27%,RSD為0.67%(n=9)。結(jié)論:該方法簡便、快速、準(zhǔn)確,適用于氫溴酸山莨菪堿片的含量及含量均勻度的測定。
