摘　　要：研究了大孔吸附树脂分离纯化黄芪中黄芪多糖的工艺条件。以黄芪多糖的吸附量和吸附率为考察指标,从中筛选树脂,并研究大孔吸附树脂分离纯化黄芪多糖的吸附性能和洗脱参数。结果表明:X-5树脂对黄芪多糖有较好的吸附分离性能,适合于黄芪中黄芪多糖的提纯,经该树脂吸附解吸,饱和吸附量可达30.83mg/g,解析率达81%。大孔树脂分离纯化黄芪多糖的纯度可达71.3%,而上柱前粗提物中黄芪多糖纯度为56.32%,说明采用该法分离纯化黄芪中黄芪多糖是可行的。To study the technological parameters of the purification process of Astragalus polysaccharides with maeroporous adsorption resin. Methods： The static adsorption capacity and adsorption ratio were used a： parameters to select the resin. The adsorptive characteristics and elution parameters of the resin were studied. Results. Resin X-5 had a good separation performance and was selected to purify Astragalus polysaecharides. The static adsorption capacity was 30.83 mg/g and the desorption ratio was 81%. Conclusion： The purity was increased from 56.32 % to 71.3%. This process was practical.
