Abstract
目的:建立HPLC法同时测定不同产地芫花药材中7个具有抗肿瘤活性的瑞香烷型二萜[yuanhuadine(1),yuanhua-fine(2),genkwadaphnine(3),yuanhuacine(2),yuanhuahine(5),yuanhualine(6),isoyuanhuadine(7)]的含量.方法:芫花以75%乙醇水溶液提取;色谱柱为ZorbaxEelipse SB-C18(250 mm×4.6 mm,5μm),流动相:乙睛-0.1%冰醋酸水,检测波长:230 nm,柱温:40℃,流速:0.8 mL/min,进样量:10μL,洗脱梯度:采用二元梯度洗脱系统,溶剂A(乙睛),B(水、0.1%冰醋酸).结果:上述7个瑞香烷型二萜的线性关系良好(r≥0.9941),平均加样回收率为98.1%~104.5%.不同生长环境的芫花中的7个成分各自含量有所差别.结论:该方法可用于中药芫花中瑞香烷型二萜的含量测定研究.
