摘    要:目的采用高效液相色谱法(HPLC)同时测定不同产地白芷中欧前胡素和异欧前胡素的含量,为更好的评价不同产地白芷的质量提供依据。方法色谱柱:L ichrospher-C18(250×4.6 mm,5μm),柱温:30℃,流动相:甲醇-水,梯度洗脱,流速为1.0 mL.m in-1。结果欧前胡素、异欧前胡素进样量分别在0.54~5.40μg、0.244~2.44μg范围内,呈现良好的线性关系。欧前胡素平均回收率99.020%,相对标准偏差(RSD)3.318%;异欧前胡素平均回收率97.528%,RSD 2.904%。欧前胡素平均含量为1.465 mg.g-1;异欧前胡素平均含量为0.575 mg.g-1。结论该测定方法简单,快速,重现性好,可作为该药材质量的控制方法。

关 键 词:白芷  高效液相色谱法  欧前胡素  异欧前胡素

Determination of contents of imperatorin and isoimperatorin in Radix Angelicae Dahuricae from different areas by HPLC
Abstract:Objective To develop a method for the determination of imperatorin and isoimperatorin in Radix Angelicae Dahuricae.Methods A HPLC method was established.Lichrospher-C18 column(250 mm×4.6 mm,5 μm)was used,with mixture of methanol and water in a gradient mode.The flow rate was 1.0 mL·min-1.Results The calibration of imperatorin was linear in range of 0.54~5.40 μg.The average recovery was 99.020%,RSD 3.318%.The calibration of isoimperatorin was linear in range of 0.244~2.44 μg.The average recovery was 97.528%,RSD 2.904%.The average contents of imperatorin and isoimperatorin were 1.465 mg·g-1 and 0.575 mg·g-1 respectively.Conclusion The method is appropriate for the detemination of Radix Angelicae Dahuricae.
Keywords:Radix Angelicae Dahuricae  high performance liquid chromatography  imperatorin  isoimperatorin
