目的：：建立高效液相色谱法测定米诺地尔片的含量及含量均匀度。方法：采用XBridge C18(250 mm ×4.6 mm,5μm )色谱柱,流动相为甲醇-0.03 mol·L-1磷酸二氢钾溶液-三乙胺(60∶40∶0.1)(用磷酸调节pH至3.5),流速为1.0 ml· min-1,检测波长为287 nm,柱温为30℃,进样量：10μl。结果：米诺地尔在8.056~32.224μg·ml-1(r=0.9999)范围内线性关系良好；平均回收率为99.68%(RSD=0.36%,n=9),3批样品的平均含量分别为100.2%,100.5%,99.8%,含量均匀度分别为5.5,6.2,4.9。结论：所用方法简便准确,重复性好,可用于控制米诺地尔片的质量。“,”To establish an HPLC method for the determination of content and content uniformity of minoxidil tablets. Methods:An Xbridge C18 column (250 mm ×4.6 mm, 5 μm)was used with methanol-0.03 mol·L-1 KH2PO4 solution -triethyl-amine(60∶40∶0. 1)(adjusting pH to 3. 5 with phosphoric acid ) as the mobile phase. The flow rate was 1. 0 ml·min-1 and the detec-tion wavelength was 287 nm. The column temperature was 30℃ and the injection volume was 10 μl. Results:There was a good linear relationship within the range of 8. 056-32. 224 μg·ml-1(r=0. 999 9). The average recovery was 99. 68%(RSD=0. 36%,n=9). The average content of 3 batches of samples was 100. 2%,100. 5% and 99. 8% and the content uniformity was 5. 5,6. 2 and 4. 9, re-spectively. Conclusion:The method is simple and accurate with good reproducibility, which can be used in the quality control of mi-noxidil tablets.
