摘　　要：目的：探讨大孔吸附树脂AB-8对银杏外种皮多糖的吸附性能及其影响因素。方法：采用单因素实验优选AB-8树脂的纯化条件。结果：以流速为1．0ml／min，原样浓度为10mg／ml，pH值为7．4～7．6之间的组合上柱，银杏外种皮多糖的纯化效果最好。结论：AB-8树脂吸附性较好，多糖洗脱容易，纯化后多糖含量达81．3％。Objective： To study the adsorption and desorption behavior of macroporous adsorbption resin AB-8 for polysaccharides in exoearp of Ginkgo biloba L. and its effect factors. Methods： The optimum purification conditions were investigated by singal factor experiments. Results： The optimum conditions were as follows： the follow rate was 1.0 ml/min, solution concentration was 10 mg/ml and the pH was 7.4-7.6. Conclusion： AB-8 have an upper adsorption capacity for polysaccharides in exocarp of Ginkgo biloba L and the elution is easy. The purification of its production is 81.3%.
