Abstract
目的 建立一种测定一类新药毛兰素乳液型注射液中毛兰素及有关物质鼓槌联苄含量的方法.方法 采用Agilent XDB C18柱(4.6mm×250mm,5μm),流动相为甲醇-乙腈-水(30:30:40).检测波长;232nm;流速:1.0mL·min-1.结果 毛兰素及有关物质鼓槌联苄达到完全分离;毛兰素在5.5625~89.0 μg·mL-1内线性关系良好(Y=13504X+2146.6,r=0.9999),平均回收率100.8%;有关物质鼓槌联苄在9.292~46.462μg·mL-1内亦有良好线性关系(Y=14.0331 X+2.3886,r=0.9999),平均回收率达99.8%.结论 本法灵敏,准确,专属性强,可用于测定注射液中毛兰素的含量和有关物质的检查.
