摘要
目的建立癃闭舒片中补骨脂素和异补骨脂素的定量方法。方法对国内3个企业生产的6个批次的癃闭舒片,采用HPLC法检测,Agilent TC-C18（2）色谱柱（250 mm×4.6 mm,5μm）,流动相是甲醇-水（43？57）,体积流量1.0 mL/min,检测波长为246 nm,柱温30℃。结果补骨脂素回归方程为：Y=84.44X＋9.994,r=0.999 9（n=12）。异补骨脂素回归方程为：Y=82.434X＋8.8952,r=0.999 9（n=12）。补骨脂素和异补骨脂素的线性范围均在4.04-151.5μg。结论本方法操作简便、准确、专属性强、稳定,可用于癃闭舒片中补骨脂素和异补骨脂素的含量测定。
Objective To establish a method for the content determination of psoralen and isopsoralen in Longbishu Pills（LBSP）. Methods HPLC was performed on the Agilent TC-C18（2） column（250 mm×4.6 mm, 5 μm） with the mobile phase of Me OH-H2O（43：57）, the flow rate was 0.8 mL/min, the detection wavelength 246 nm, and the column temperature was 30℃. Results The element regression equation of psoralen was Y=84.44 X ＋ 9.994, r=0.999 9（n=12）. The element regression equation of isopsoralen was Y=82.434X＋8.895 2, r=0.999 9（n=12）. The concentrations of psoralen and isopsoralen were within the range of 4.04—151.5 μg. Conclusion The method is simple, reliable, and specific, with good reproducibility, and could be used to determine the content of psoralen and isopsoralen in Longbishu Pills.
