摘要
目的建立盐酸多沙普仑葡萄糖注射液的高效液相色谱含量测定方法。方法采用COSMOSIL C18(150 mm×4.6 mm,5μm)色谱柱,以0.82μg/L醋酸钠溶液(用冰醋酸调pH值为4.5)-乙腈=70∶30为流动相,检测波长为214 nm。结果盐酸多沙普仑浓度在13~91μg/ml范围内呈良好的线性关系(r=0.999 8)。平均加样回收率为99.3%,RSD为0.81%(n=9)。结论此方法简便、准确、灵敏度高、专属性强。
Objective To establish an HPLC method for determination of doxapram hydrochloride glucose injection. Methods COSMOSIL C18 (150 mm× 4.6 mm ,5 μm) column was adopted. The mobile phase consisted of 0.82 p,g/L CH3COONa( using Gla- cial acetic acid adjust to pH 4.5 )-acetonitrile (70:30). The detection wavelength was 214 nm. Results The linearity of doxapram hydrochloride concentration was in the range of 13 - 91μg/ml( r = 0. 999 8 ). The average recovery was 99.3 % , RSD = 0.81% ( n = 9). Conclusion The method was simpleaccurate and sensitive with high specificity.
