The invention discloses a method for extracting a bighead atractylodes rhizome extract. The method comprises the following steps: placing 1 part of bighead atractylodes rhizome in a drying box to be dried to a moisture content of less than or equal to 5% of bighead atractylodes rhizome, and grinding; irradiating by using electron beams with intensity of 10kGy; adding bighead atractylodes rhizome powder to ethanol with concentration of 70% and pH value of 5, subjecting to ultrasound in a water bath for 5min, stirring for 1h, subjecting to suction filtration to obtain a first filtrate and first filter residues, and subjecting the first filtrate to rotary evaporation to obtain a mixture A; placing the first filter residues in 8 parts of organic solvent, subjecting to ultrasound in a water bath for 5min, stirring for 30min, subjecting to suction filtration to obtain a second filtrate, and subjecting the second filtrate to rotary evaporation to obtain a mixture B; adding 50 parts of deionized water to second filter residues, cooking for 10 minutes, cooling to 30 DEG C, subjecting to suction filtration to obtain a third filtrate, distilling under reduced pressure to obtain a mixture C, placing the mixtures A, B and C in 15 parts of aqueous ethanol in 15 parts of absolute ethanol, placing in a 50 DEG C water bath, stirring for 20min, placing in a refrigerator, keeping stand for 10h at a temperature of 5 DEG C, subjecting to suction filtration, and filtering out a liquid to obtain a bighead atractylodes rhizome extract. The method provided by the invention can be used for efficiently and safely extracting nutrients in the bighead atractylodes rhizome.
