Abstract

The invention relates to a preparation method of a red raspberry extract, and belongs to the field of processing of health food. The technical scheme of the invention is as follows: 1, selecting red raspberry fruits for preprocessing so as to obtain dried red raspberry fruits processed with salt water; 2, smashing the dried red raspberry fruits processed with salt water and sieving the smashed red raspberry fruits so as to obtain red raspberry fruit powder; 3, extracting the red raspberry fruit powder with ethanol and post-processing the red raspberry fruit powder so as to obtain a coarse red raspberry extract; 4, separating and purifying the coarse red raspberry extract by virtue of macroporous resin chromatography so as to obtain a pure product of the coarse red raspberry extract; and 5, separating and purifying the pure product of the coarse red raspberry extract by virtue of gel chromatography, and freeze-drying so as to obtain the red raspberry extract. The red raspberry extract has good functions of reducing blood fat, decreasing blood sugar, reducing blood pressure, relieving fatty liver, enhancing body immunity, tonifying kidney, securing essence and reducing urination, controlling weight, regulating metabolism and the like; and the red raspberry extract is broad in market development prospect.
