Extraction method of wolfberry extract

Abstract

The invention discloses a wolfberry extract obtaining method. The method comprises the steps of placing a part of wolfberry in a drying box, conducting drying till the water content of wolfberry is smaller than or equal to 5%, and conducting grinding; conducting irradiation with electronic beams with the intensity of 10 kGy; adding wolfberry powder to ethyl alcohol with the PH value of 5, conducting water bath ultrasonic treatment for 5 min, conducting stirring for 1 h, conducting suction filtration to obtain first filtrate and first filter residues, and conducting rotary evaporation on the first filtrate to obtain a mixture A; placing the first filter residues in eight parts of organic solvent, conducting water bath ultrasonic treatment for 5 min, conducting stirring for 30 min, conducting suction filtration to obtain second filtrate, and conducting rotary evaporation on the second filtrate to obtain a mixture B; adding 50 parts of deionized water to second filter residues, conducting cooking for 10 min, conducting cooling to 30 DEG C, conducting suction filtration to obtain third filtrate, conducting reduced pressure distillation to obtain a mixture C, placing the mixture A, the mixture B and the mixture C in 15 parts of absolute ethyl alcohol, placing the mixture in a water bath which is 50 DEG C, conducting stirring for 20 min, placing the product in a refrigerator to stand for 10 h at 5 DEG C, conducting suction filtration, and filtering out liquid to obtain wolfberry extract. In this way, nutrients in wolfberry are extracted efficiently and safely.
