Abstract: 目的 建立高效液相色谱法同时测定蒺藜饮片中槲皮素、山柰素和异鼠李素含量的方法.方法 用Kromasil C18(4.6 mm×250 mm,5μm)色谱柱,甲醇-0.1%甲酸溶液(47∶53)为流动相,检测波长368 nm,流速1.0mL· min-1,柱温25℃.结果 槲皮素、山柰素和异鼠李素分别在0.58 ~29.0、0.292 ~ 14.6、0.248 ~ 12.4 μg·mL-1范围内呈良好线性关系(r >0.999 7),平均回收率分别为100.91%、99.44%、99.20%,RSD分别为1.91%、1.85%、1.73%.结论 该方法简便、快速、准确度高,可为蒺藜饮片的质量控制和炮制研究提供参考依据.
