【摘要】:目的:建立高效液相色谱法测定安立生坦片中有关物质。方法:采用安捷伦ZORBAX SB-Aq(4.6mm×250 mm,5μm)色谱柱,流动相A为5 mmol·L~(-1)磷酸二氢钾溶液(p H 3.0),流动相B为乙腈,以1.0m L·min~(-1)的流速进行梯度洗脱,检测波长为210 nm,柱温25℃,以自身对照法测定安立生坦片中有关物质。结果:安立生坦与各杂质及降解产物能够完全分离(分离度大于2.0);供试品溶液在24 h内稳定性良好;安立生坦和2-羟基-3-甲氧基-3,3-二苯基丙酸(杂质A)、(S)-1-(4-氯苯基)乙胺(杂质B)、3,3二苯基-2,3-环氧丙酸甲酯(杂质C)、2-羟基-3-甲氧基-3,3二苯基丙酸甲酯(杂质D)、4,6-二甲基-2-甲基-磺酰嘧啶(杂质E)和4,6-二甲基-2-(2,2-二苯基-乙烯氧基)嘧啶(杂质F)的定量限分别为0.66、0.64、0.65、1.31、0.65、0.63和1.32 ng,相对校正因子分别为1.00、1.08、2.20、1.09、1.10、2.54和1.07;安立生坦质量浓度在0.5~5.0μg·m L~(-1)范围内线性良好(r0.999 9),各杂质质量浓度在0.125~2.5μg·m L~(-1)范围内线性良好(r0.999),杂质加样回收率(n=9)在95.8%~103.7%之间;重复性和中间精密度符合规定。经检测,3批安立生坦片中杂质A含量均为0.01%。结论:经验证本方法准确、灵敏,精密度高,耐用性和专属性强,可用于安立生坦片中有关物质的测定。
