Method for extracting annonaceous acetogenin from atemoya

The invention discloses a method for extracting annonaceous acetogenin from atemoya, and belongs to the field of an annonaceous acetogenin extracting processes. The method comprises the following steps: pretreating an extracted raw material; drying the pretreated raw material, and then crushing by using a vacuum crusher to obtain crushed raw material powder; placing the crushed raw material powderinto a quick freezer for quick freezing to obtain ice powder, crushing the ice powder by using a crusher, unfreezing the crushed ice powder, and drying steam to obtain dry fine powder; placing the dried fine powder and water into a vacuum stirring tank for vacuum stirring; filtering to remove filter residues, and pouring filtrate into an extraction kettle for extraction; and collecting the extract after extracting for 2vh, extracting the extract with chloroform for 4 times, combining chloroform layers, carrying out vacuum filtration, recovering a solvent under reduced pressure at the temperature of 45 DEG C, and dryi
