简介:建立同时测定西洋参中7种人参皂苷含量的快速检测方法.方法:采用超高效液相色谱法,ACQUITYUPLCBEHC18色谱柱(2.1×50mm,1.7μm),以乙腈-水为流动相,梯度洗脱,流速:0.5ml/min,柱温35℃,进样体积2μL,检测波长203nm.结果:人参皂苷Rg1、Re、Rb1、Rc、Rb2、Rb3、Rd存在良好线性关系,线性范围分别为0.0067~0.334mg/ml,0.0151~0.756mg/ml,0.0130~0.649mg/ml,0.0043~0.217mg/ml,0.0044~0.221mg/ml,0.0085~0.424mg/ml,0.0086~0.43mg/ml.结论:该方法准确、重现性好,可用于西洋参中人参皂苷含量测定.
简介:目的建立反相高效液相色潜法测定泽兰中木犀草素-7-0-β-D-葡萄糖苷的含量。方法采用AlltimaTM—C18(250minx4.6mm,51.Lm);以乙腈-0.2%磷酸水溶=20:80进行等度洗脱,流速为1.0ml/min,检测波长为350mm,柱温为35℃。结果木犀草素-7-0-β-D-葡萄糖苷的线性范围为0.412-10.30μg(r=0.9999),平均回收率为100.25%。结论该方法结果准确、简便可行、重复性好,可为泽兰的质量控制提供依据。
