摘　　要： 研究微波辅助提取花生壳中木犀草素的最佳工艺条件。采用HPLC法测定木犀草素含量,以提取率为指标,应用单因素和正交试验,分别考察微波辅助提取时间、料液比、提取时间等3个因素影响,并将筛选工艺与目前文献的乙醇提工艺进行对比分析。结果表明,微波辅助提取木犀草素的最佳工艺条件:微波时间为2.0min,料液比为1∶6,提取时间为4h。与传统乙醇提取工艺相比,微波辅助提取工艺提取花生壳中木犀草素的提取率提高了4.53倍。 To determine the optimum conditions for microwave assisted extraction of luteolin from peanut hull. The luteolin content was determined by HPLC method. The effects of microwave treatment time, ratio of material to solvent and extraction time on luteolin extraction efficiency were investigated by single factor and orthogonal tests. The microwave assisted extraction technology was evaluated by comparison with ethanol extraction technology reported in current references. The optimum microwave assisted extraction conditions were microwave treatment time 2.0min, ratio of material to solvent 1：6 and extraction time 4h. The luteolin yield of microwave assisted extraction was 4.53 times higher than that of traditional ethanol extraction.
