Abstract
目的:建立RP-HPLC同时测定白鲜皮中白鲜碱、黄柏酮和梣酮含量的方法.方法:采用RP-HPLC,70%乙醇超声提取,色谱条件:色谱柱Alhima C18(4.6 mm×250 mm,5μm),保护柱All-GuardTM C18(4.6 mm ×7.5 mm,5μm),流动相乙腈-0.1%磷酸梯度洗脱,流速1.0 mL/min,进样量10 μL,柱温25℃,检测波长238 nm.结果:该3种成分分离良好,线性范围依次为0.4~16.0,10~400和1.6~64.0 mg/L,加样回收率分别为99.95%,98.91%,100.02%,RSD分别为:1.81%,1.83%,2.62%.结论:本方法简单、快捷,重现性好,准确率高,可用于白鲜皮药材的质量控制.
