【摘要】 采用正交实验法(采用L9(34))对桑叶中黄酮多酚类物质提取条件进行了分析,优化乙醇浓度、料液比、提取时间和温度等因素对桑叶中总黄酮与桑多酚提取率的影响。结果表明:当料液比1:60,乙醇体积浓度60%,提取温度100℃,提取时间2.5 h,从桑叶中提取的总黄酮与桑多酚的提取率达最高。更多还原

【Abstract】 By using the orthogonal experiment method(using L9(34) to optimize the ethanol concentration,ratio of material to liquid,extraction time and temperature on the flavonoids in the mulberry leaves and mulberry polyphenol extraction rate influence.The results show that: when the liquid than 1: 60,60% volume of ethanol concentration,extraction temperature 100 ℃,extraction time of 2.5 h,total flavonoids extracted from mulberry and mulberry polyphenol extraction rate was the highest.更多还原
