摘要
目的建立多西他赛囊袋张力环的含量测定方法。方法采用高效液相色谱法,色谱柱:C18(5μm,4.6×150mm),流动相:乙腈-水(60∶40),流速:1m L·min^(-1),柱温:35℃,检测波长:232nm,进样量:20μL。结果多西他赛在0.5μg·m L^(-1)~3.5μg·m L^(-1)浓度范围内线性关系良好,r=0.9998,高中低浓度的平均回收率为99.15%(n=9),RSD值分别为2.09%。结论该含量测定方法准确度高,专属性强,操作简便,可作为多西他赛囊袋张力环的含量测定方法。
OBJECTIVE To develop rings. METHODS High performance liquid c a method for the determination of docetaxel capsule tension hromatography was used. Chromatographic column : C18 (5μm,4.6×150mm), mobile phase: acetonitrile-water ( 60:40 ), flow rate: 1mL · min -1, column temperature: 35 ℃, detection wavelength :232nm, sample volume : 20μ L. RESULTS The calibration curve was linear ( r = 0. 9998 ) within the range of 0. 5μg ·mL-1- 3.5μg · mL-1. The average recovery rate was 99. 15% ( n = 9 ) , RSD = 2.09%. CONCLOUSION This determination method, which is high accuracy, strong specificity and simple operation, can be suitable for determination of docetaxel capsular tension rings.
