摘　　要：目的：建立HPLC法测定芪贞慢咽宁颗粒中木蝴蝶苷B。方法采用Kromasil 100-5 C18色谱柱（250 mmx4.6 mm，5μm），流动相甲醇–0.1%磷酸（38∶62），检测波长276 nm，体积流量1.0 mL/min，柱温30℃，进样量5μL。结果木蝴蝶苷B在0.0646-1.2920μg与峰面积线性关系良好。木蝴蝶苷B平均回收率为100.67%，RSD值为1.12%。结论本法测定快速、结果准确、重复性好、专属性强，可用于测定芪贞慢咽宁颗粒中木蝴蝶苷B。Objective To establish an HPLC method to determine oroxin B in Qizhen Manyanning Granules. Methods The determination was carried out on Kromasil 100-5 C18 column （250 mm x 4.6 mm, 5 μm）. The mobile phase consisted of methanol -0.1%phosphoric acid （38∶62）, and UV detection wavelength was set at 276 nm. The flow rate was 1.0 mL/min and the column temperature was 30℃with the injection volume of 5 μL. Results There was a good linear relationship between peak area and the content of oroxin B in the rang of 0.064 6—1.292 0 μg. The average recovery of oroxin B was 100.67%with RSD 1.12%. Conclusion The method is rapid, accurate and reproducible for the quantification of oroxin B in Qizhen Manyanning Granules.
