【摘要】:本研究建立了同時測定中藥白術(shù)中白術(shù)內(nèi)酯Ⅰ,Ⅱ,Ⅲ含量的高效液相色譜法,結(jié)果表明白術(shù)內(nèi)酯Ⅰ,Ⅱ,Ⅲ進樣量分別在76~760 ng,87~870 ng,75~750 ng范圍內(nèi)線性關(guān)系良好,白術(shù)甲醇超聲提取液中白術(shù)內(nèi)酯Ⅰ,Ⅱ,Ⅲ平均加樣回收率分別為100.20%(RSD=1.8%),100.10%(RSD=1.2%),99.68%(RSD=0.84%),白術(shù)甲醇回流提取液中白術(shù)內(nèi)酯Ⅰ,Ⅱ,Ⅲ平均加樣回收率分別為100.67%(RSD=0.88%),100.06%(RSD=0.67%),100.67%(RSD=1.7%).該含量測定方法簡單、快速、準確、靈敏度高、重復(fù)性好,可用于白術(shù)藥材的質(zhì)量控制.超聲提取法對白術(shù)內(nèi)酯Ⅰ,Ⅱ,Ⅲ的提取效率均高于加熱回流提取法.
