【摘要】:比较延龄草与吉林延龄草药材根茎与须根间主要成分的含量差异,利用HPLC-CAD同时测定了3种主要成分重楼皂苷Ⅶ、偏诺皂苷元-3β-O-α-L-吡喃鼠李糖基-(1→4)-[α-L-吡喃鼠李糖基-(1→2)]-O-β-D-葡萄糖、重楼皂苷Ⅵ的含量。色谱条件:TSK gel ODS(4.6 mm×250 mm,5μm)色谱柱,乙腈-水(43∶57)等度洗脱,流速为1 mL·min~(-1),进样量为20μL。电雾式检测器(CAD):工作气压为35 psi(1 psi=6.895 kPa),雾化器温度为35℃。3种甾体皂苷良好分离,线性关系、稳定性、精密度、重复性、加样回收试验均符合中药质量分析要求。运用IBM SPSS Statistics 20分析软件进行主成分分析,结果显示,头顶一颗珠的来源包含了2种延龄草属植物,且吉林延龄草为主要资源;7批延龄草样品和9批吉林延龄草的根茎之间3种皂苷成分的含量存在不显著差异;但是根茎与须根之间3种皂苷成分的含量存在显著的差异。
