摘　　要：利用重庆皱皮木瓜果渣进行总黄酮提取工艺优化研究。在单因素实验的基础上,考察乙醇浓度、提取温度、提取时间、料液比、提取方法等因素对皱皮木瓜果渣中总黄酮提取效果的影响,并结合正交实验优选出最佳提取条件。影响皱皮木瓜果渣总黄酮提取的因素大小顺序为:提取温度>乙醇浓度>提取时间>料液比,其中温度对总黄酮得率影响较明显。最佳提取工艺:浓度50%乙醇为提取溶剂,提取温度60℃,料液比1∶30(g·m L-1),提取时间80min;在最佳工艺条件下,皱皮木瓜果渣中总黄酮得率约为0.527%。本实验确定的优化工艺简便准确易行。To optimize the extraction process conditions for total fiavonoids from the Chaenomeles Speciosa pomace of Chongqing.On the basis of the single-factor test, effects of solid-liquid atio, ethanol concentration, extraction time, extraction temperature and extraction times on the extraction rate were studied by taking the content of total flavonoids as the index.The influence degree of four factors on the extraction rate of total flavonoids was in the order of extraction temperature 〉 ethanol concentration 〉 extraction time 〉 solid-liquid ratio. Among them,temperature had relatively significant impacts on the yield rate of total flavonoids from Chaenomeles Speciosa pomace. The best extraction technology： concentration of 50% ethanol as xtraction solvent, 60℃ extraction temperature, 1：30 （ g·mL^-1） solid-liquid ratio, 80min extracting time. Under this condition, the yield was 0.527%.This method was simple convenient and accurate for the detection of total flavonoids.
