摘要: 目的 建立HPLC同时测定复方五味含片中葛根素、甘草苷、甘草酸铵、五味子醇甲、五味子甲素、五味子乙素6种成分含量的方法。方法 KromasiL C18柱(250 mm×4.6 mm,5 μm);流动相:乙腈-0.05%磷酸水溶液,梯度洗脱;流速1.0 mL/min;柱温30 ℃,检测波长250 nm。结果 葛根素、甘草苷、甘草酸铵、五味子醇甲、五味子甲素、五味子乙素分别在0.031 0~0.154 9、0.013 7~0.068 5、0.042 4~0.211 8、0.017 4~0.087 1、0.001 8~0.009 1、0.013 6~0.068 1 mg/mL线性范围良好;相关系数均大于0.999 5;平均加样回收率分别为98.6%、100.4%、98.3%、98.3%、96.8%、99.4%;RSD分别为2.6%、2.8%、1.2%、2.3%、0.9%、2.5%。结论 该方法简便、重复性好,可用于复方五味含片的质量控制。Abstract: OBJECTIVE To establish a method to simultaneously determine puerarin, liquiritin, ammonium glycyrrhetate, schizandrol, deoxyschisandrin, and schizandrin B in compound wuwei tablet by HPLC. METHODS The elusion was performed on Kromasil C18(250 mm×4.6 mm, 5 μm) column. The mobile phase was composed of acetonitrile and 0.05% H3PO4 with gradient elution. The detection wave length was 250 nm, the flow rate was 1.0 mL/min and the column temperature was maintained at 30 ℃. RESULTS Puerarin, liquiritin, ammonium glycyrrhetate, schizandrol, deoxyschisandrin, schizandrin B are all linear in the range of 0.031 0~0.154 9,0.013 7~0.068 5,0.042 4~0.211 8,0.017 4~0.087 1,0.001 8~0.009 1,0.013 6~0.068 1 mg/mL respectively. Their average recoveries were 98.6%,100.4%,98.3%,98.3%,96.8%,99.4% and RSD of the above six components were 2.6%,2.8%,1.2%,2.3%,0.9%,2.5%. CONCLUSION The method is easy to perform and accurate and practical so that it can be used to determine the six components in the compound wuwei buccal tablets.
