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
glucoside with 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.
