摘　　要：研究了大叶藻中黄酮的乙醇提取工艺,以大叶藻中黄酮提取率为考察指标,通过单因素和正交实验,考察提取温度、乙醇浓度、固液比、提取时间对黄酮提取率的影响,结果确定最佳提取工艺条件为:提取温度55℃,提取固液比1∶30,提取溶剂乙醇浓度85%,提取时间3h。在最佳提取条件下,提取率可高达1.80%。The flavonoids were extracted from Zostera marina L.with ethanol.The quantity proportion of fiavonoids extracted from Zostera marina L. was investigated. Some factors, such as extraction temperature, ethanol concentration,the ratio of solid to liquid, extracting time were studied as the main factors on the extracting quantity.The single factor and orthogonal experiments showed that the optimum extraction conditions were as follows：extracting temperature 55℃, the ratio of solid to liquid 1：30, ethanol concentration 85%, extracting time 3 hours.Under the best condition,the extraction rate can be as high as 1.80%.
