Abstract
目的:为了更好地评价药食两用的中药党参,建立准确快速的 RP-HPLC 法测定党参药材中党参炔苷的含量。方法:采用 Kromasil C_(18)柱(4.6 mm×200 mm,5μm),流动相为乙腈-水(28:72),流速为1.0 mL·min~(-1),检测波长为267 nm。结果:党参炔苷在0.05~0.60μg范围内线性关系良好,r=0.9998,回归方程为 Y=2.26×10~6X-2.75×10~4,平均回收率为98.83%,RSD 为0.95%(n=6)。结论:本法简便快速,准确度和重现性好,可用于党参中党参炔苷的含量测定。山西党参药材中,陵川产的五花芯党参含党参炔苷的量最高。
