Efficient extraction method for tea polyphenol

The invention discloses an efficient extraction method for tea polyphenol. The method includes: subjecting picked fresh tea to high temperature sterilization, and then performing drying and crushing;mixing the crushed tea powder with a 30DEG C 80% ethanol solution in a mass ratio of 3:1, and conducting soaking for 40min, and heating the soaking solution to boiling to obtain an ethanol mixed solution; lowering the temperature of the ethanol mixed solution to about 70DEG C, adding ethyl acetate with a mass accounting for half of the ethanol mixed solution, maintaining the temperature at 60-70DEG C, and conducting stirring for 20min, filtering the stirred solution to remove slag, thus obtaining a tea polyphenol extract liquid; adding distilled water into the tea polyphenol extract liquid forwashing, performing concentration, then distillation recovery of ethanol and ethyl acetate, thus obtaining a tea polyphenol finished product. Compared with the prior art, the method provided by the invention has the advantage
