A preparation method for a 
traditional Chinese medicine composition for improving 
immunity of 
livestock and poultry relates to a 
traditional Chinese medicine composition. The preparation method comprises the following steps: taking acanthopanax root, crushing and sifting; adding 
ethanol to dynamically soaking and performing 
reflux extraction; depressurizing the supernatant and recycling 
ethanol from the supernatant until no 
alcohol smell is detected; adding 
ethanol of low concentration to be prepared into 
crude drug; centrifuging and putting supernatant on 
macro-porous absorption resin column; using water to elute reaction negativity and successively eluting by ethanol, then collecting ethanol and eluted part of ethanol and combining to obtain acanthopanax total 
glucoside; taking 
astragalus root and extracting with ethanol, then mixing with acanthopanax root dregs; filtering and recycling ethanol from filter liquid to obtain total 
polysaccharide; combining acanthopanax total glucosidewith total 
polysaccharide and filling into bottles, then sterilizing to obtain injection liquid. The invention uses the technical solution in combination with ethanol extraction method and 
water extraction method to extract acanthopanax total 
glucoside, total 
polysaccharide and 
astragalus root polysaccharide. The acanthopanax total 
glucoside, total polysaccharide and 
astragalus root polysaccharide are added with 
excipient and processed by 
common procedures or added with pharmaceutically acceptable 
excipient to be made into clinically acceptable dosage forms.
