摘　　要：使用超声波法提取川楝(Melia toosendan)子中的阿魏酸,采用HPLC法检测阿魏酸的含量。设计单因素试验,考察了提取溶剂、提取温度、料液比、提取时间、提取次数等试验条件对阿魏酸提取率的影响,以优化提取条件。优化的超声提取条件为,体积比为95∶5的甲醇-甲酸为提取溶剂,料液比1∶30(m∶V,g/mL),提取温度55℃,提取时间30 min,提取次数2次,最高提取率达0.012 6 mg/g。Ferulic acid was extracted from Melia toosendan by ultrasonic method and determined by HPLC.Single factor tests were adopted to analyze the effects of factors including extraction solvent,extraction temperature,solid to liquid ratio,extraction time,and extraction times on the yield of ferulic acid.The optimum ultrasonic extraction conditions were using methanol-formic acid（volume ratio 95∶5） as the extraction solvent;Solid to liquid ratio at 1∶30（m∶V,g /mL）;Extraction temperature,55 ℃;Extraction time,30 min;And extracting for twice.The yield of ferulic acid under these conditions was 0.012 6 mg / g.
