【摘要】:目的建立测定甲氧氯普胺(MCP)鼻腔喷雾剂含量和有关物质的HPLC检测方法。方法采用Agilent TC-C18柱(250 mm×4.6 mm,5μm),流动相为乙腈-磷酸盐缓冲液(取0.05 mol/L磷酸二氢钾溶液,加三乙胺5 ml,用磷酸调至p H 4.0)(19∶81),检测波长为275 nm,柱温30℃,流速为1.0 ml/min。结果与结论在建立的色谱条件下,MCP与有关物质峰基线分离,MCP浓度在10~200μg/ml范围内线性关系良好,r=0.9999,回收率为100.3%~101.6%,RSD为0.68%(n=9),MCP检出限0.3 ng。该方法准确、可靠,重复性较好,可作为MCP鼻腔喷雾剂的质量控制方法。
[Abstract]:Objective to establish a HPLC method for the determination of metoclopramide in nasal spray and related substances. Methods the Agilent TC-C18 column was used to determine the content of methoxyclopramide and its related substances. Methods the mobile phase consisted of acetonitrile-phosphate buffer solution (0.05 mol/L potassium dihydrogen phosphate solution). Adding triethylamine 5 ml, adjusted with phosphoric acid to 19: 81C, the detection wavelength is 275 nm, the column temperature is 30 鈩,
