[Objective] The study aimed to research the technology of flavonoids extraction from Auricularia auricula by ethanol extraction method. [Method] Hie factors that affect the extraction ratio were investigated by single factor and orthogonal experiments, including the liquid-to-solid ratio, the concentration of solvent, extraction time and extraction temperature. [ Result] The optimum conditions were as follows:solid-liquid ratio was 1=7, ethanol concentration was 80% , extraction time was 6 h and temperature was SO CC. On this condition, the extraction ratio was 0.43%. [Conclusion] The process conditions were suit for flavonoids extraction from Auricularia auricula.%[目的]研究乙醇浸提法提取黑木耳中黄酮类化合物的工艺.[方法]采用单因素试验和正交试验检测料液比、乙醇浓度、提取时间和提取温度对黑未耳黄酮类化合物提取得率的影响.[结果]最佳提取条件为:料液比1:7,乙醇浓度80％,提取时间6h,提取温度50℃,在该工艺条件下提取率达到0.43％.[结论]该工艺条件下提取率较高,适于提取黑木耳中黄酮类化合物.
