摘    要:目的建立HPLC法同时测定葛根芩连片中黄芩苷和葛根素的含量。方法用Agilent Eclipse XDB—C18柱(5μm,4.6mm×250mm);流动相A为甲醇,流动相B为0.2%磷酸溶液,二元梯度洗脱,检测波长:277nm;流速:1ml·min-1;柱温:30℃。结果黄芩苷进样量在0.1794~3.5870μg范围内,葛根素进样量在0.1783~3.5650μg范围内线性关系良好,平均加样回收率分别为98.7%和98.8%。结论该法灵敏、简便、准确,可用于葛根芩连片质量控制。关键词:高效液相色谱法;葛根芩连片;梯度洗脱;黄芩苷;葛根素

关 键 词:高效液相色谱法  葛根芩连片  梯度洗脱  黄芩苷  葛根素

Abstract:Objective To establish a method for determination of baicalin and puerarin in gegenqinlian tablets by HPLC.Methods The Agilent Eclipse XDB-C18 column(5 μm,4.6 mm×250 mm) was used.The mobile phase A consisted of methanol and the mobile phase B 0.2% phosphoric acid solution.The flow rate was 1.0 ml ·min-1.The detection wavelength was 277 nm and the column temperature was 30℃.Results The linear range of baicalin was 0.179 4~3.587 0 μg and range of puerain was 0.178 3~3.565 0 μg.The average recovery rate was 98.7% and 98.8%.Conclusion The method is convenient,accurate,which can be used for determination of baicalin and puerain in gegenqinlian tablets.
Keywords:HPLC  gradient elution  gegenqinlian tablets  baicalin  puerarin
