摘    要:目的建立清热镇咳糖浆中白花前胡甲素的测定方法。方法采用反相高效液相色谱法,色谱柱为Diamonsil-C18柱,流动相为乙腈-水(体积比68:32),流速为1.0mL·min^-1,检测波长为321nm,柱温为30℃。结果白花前胡甲素质量浓度在4.4-27.5μg·mL^-1间具有良好的线性关系(r=0.9995),平均回收率为99.4%(n=6)。结论该法可用于清热镇咳糖浆中白花前胡甲素的含量测定。

关 键 词:清热镇咳糖浆  白花前胡甲素  高效液相色谱法  含量测定

Abstract:Objective To establish a method for determination of praeruptorin A in Qingre Zhenke syrup. Methods A HPLC method was performed on the chromatographic column of Diamonsil-C,s at a flow rate of 1.0 mL · min^-1. The mobile phase was a mixture of aeetonitrile-water (68:32). The column temperature was 30 ℃, and the detection wavelength was 321 nm. Results The linear range of praeruptorin A was 4.4-27.5 μg · mL^-1 (r= 0.999 5). The average recovery for praeruptorin A was 99.4% (n = 6). Conclusion The method could be used for the auantitative determination of the nrenaralion.
Keywords:Qingre Zhenke syrup  praeruptorin A  HPLC  content assay
