摘要
目的建立HPLC法测定丹芪和血片中补骨脂素和异补骨脂素的含量。方法采用Sim-Pack C18柱,甲醇-水(45∶55)为流动相,柱温25℃,流速1 ml·min^-1,检测波长为247 nm。结果补骨脂素和异补骨脂素分别在5.65~56.5 mg·L^-1,4.52~45.2 mg·L^-1范围内线形关系良好,相关系数分别为r补骨脂素=0.9998,r异补骨脂素=0.9996。两组份的回收率分别为补骨脂素99.42%,RSD=1.64%;异补骨脂素98.68%,RSD=2.31%。结论本法可同时测定补骨脂素和异补骨脂素,方法简便、准确、可作为制剂的定量分析方法。
Aim To establish a reversed-phase HPLC method for the determination of psoralen and isopsoralen in danqihexue tablets.Methods The contents of psoralen and isopsoralen were assayed on a Sim-Pack C18 column with a mobile phase of methanol –water(45∶55) at a column temperature of 25 ℃.The flow rate was 1.0 ml·min^-1.The detection wavelength was at 247 nm.Results The linear ranges of psoralen and isopsoralen were 5.65~56.5 mg ·L^-1(r=0.999 8) and 4.52~45.2 mg ·L^-1(r=0.999 6) respectively.Their recoveries were 99.42%(psoralen) and 98.68%(isopsoralen).Their RSD were 1.64%(posralen) and 2.31%(isopsoralen).Conclusion This method is simple,quick,reproducible,and can be used for the quantitative analysis.
