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 eoncentration, extraction temperature 100 ℃, extraetlon time of 2.5 h, total flavonoids extracted from mulberry and mulberry polyphenol extraction rate was the highest.
