摘　　要：本试验旨在探讨黄芪多糖分级组分对鸡血清中IL-2含量的影响。将黄芪多糖经过不同浓度的乙醇进行分级沉淀,得到3个分级组分:A1、A2、A3;将320只鸡随机分为8组,分别皮下注射A1、A2、A3、A1+A2,A1+A3、A2+A3、A1+A2+A3和蒸馏水,每隔7 d采血检测血清中IL-2的含量。结果表明,A2、A3、A2+A3、A1+A2+A3能显著提高血清中IL-2含量。黄芪多糖免疫功能的有效组分为A2、A3,尤以A2作用显著。To investigate the effect of rating polysaccharides by alcohol in astragalus polysaccharides on the serum interleukin-2 contents in chickens.By using three different concentration levels of alcohol to get rating polysaccharides in APS： A1,A2,A3;320 one-day-old chickens were randomly divided into eight groups,experimental groups and control group were hypodermic injected A1,A2,A3,A1＋A2,A1＋A3,A2＋A3,A1＋A2＋A3 and distilled water separately for seven consecutive days,and then draw blood on the 22nd,29th,36th,43rd,50th,57th day to detect serum interleukin-2 contents,and evaluate the immune adjuvant effect of rating polysaccharides.A2,A3,A2＋A3,A1＋A2＋A3 can increase serum interleukin-2 contents.The valid targets of APS are A2,A3.
