Abstract: 目的 建立高效液相色谱(HPLC)法同时测定紫苏子中迷迭香酸、芹菜素和木犀草苷含量的方法.方法 色谱柱为Agilent Eclipse C18色谱柱(4.6 mm×250 mm,5μm),以甲醇-0.1%冰醋酸溶液为流动相,梯度洗脱;流速:1.0 mL·min-1,检测波长320 nm;柱温30℃.结果 迷迭香酸的含量在0.0583~2.915μg范围内呈良好的线性关系(r=1.0000),平均加样回收率为99.84%,RSD为0.25%(n=6);芹菜素的含量在0.0585~2.925μg范围内呈良好的线性关系(r=1.0000),平均加样回收率为99.83%,RSD为0.77%(n=6);木犀草苷的含量在0.0596~2.980μg范围内呈良好的线性关系(r=1.0000),平均加样回收率为99.39%,RSD为1.07%(n=6).结论 本方法简单快速、灵敏度高、相对更安全,可用于紫苏子中迷迭香酸、芹菜素和木犀草苷含量的同时测定.
