Abstract
目的:建立复方甜茶降脂合剂的质量标准.方法:利用薄层色谱法(TLC)对复方甜茶降脂合剂处方中的甜茶、菊花进行定性鉴别;采用高效液相色谱法测定复方甜茶降脂合剂中甜叶悬钩子苷.色谱条件:色谱柱为Diamonsil C18(250 mm ×4.6 mm,5μm),流动相为甲醇-水,梯度洗脱;检测波长为208 nm;进样量为15μL,流速为0.8 mL·min-1;柱温为25℃.结果:在薄层色谱中能检出甜茶和菊花,甜叶悬钩子苷线性范围为1.005 ~ 6.030 μg,加样回收率为96.29%(RSD为1.73%,n=9),10批次复方的平均含量为0.008 0mg·mL-1.结论:所建立的方法稳定可靠,可有效控制该合剂的质量.
