摘要
目的：观察大孔吸附树脂分离金银花多糖时的脱色作用。方法采用单因素试验，以脱色率和多糖含量作为评价指标，比较HPD-400A、AB-8、HPD-750、HPD-100、D3520、D301T、S8等7种不同型号大孔吸附树脂在温度、多糖浓度、pH值、吸附流速、洗脱剂5个方面对金银花多糖脱色效果的影响。结果 S8大孔吸附树脂对金银花多糖的脱色率和保留率高。最佳工艺为40℃，多糖浓度为5 mg/ml， pH值为6，流速为1 ml/min，洗脱剂为pH6的蒸馏水。在该条件下脱色率为83.2%，多糖含量为72.1%。结论 S8大孔树脂纯化金银花多糖可获得较高的脱色率和多糖含量。
Objective To study the effect of macroporous adsorptive resins on the decoloration technology ofLonicera japonica Thunb. polysaccharides（FLP）.Methods The effects of 6 kinds of macroporous adsorptive resins i.e. HPD-400A, AB-8, HPD-750, HPD-100, D3520, D301T, S8 on the decolorization technology ofLonicera japonica Thunb. polysaccharides were compared with single factor test in terms of temperature, polysaccharide concentration, pH, adsorption flow, and eluant.Results The decolorization rate and polysaccharide retention rate of S8 were optimal. The best decoloration conditions were as follows： temperature of 40℃, polysaccharide concentration of 5 mg/ml, pH value of 6, flow rate of 1 ml/min, distilled water with pH=6 as eluant. The adsorption rate was 83.2%,and polysaccharide retention rate was 72.1%.Conclusion High decolorization ratio and the high retention rate ofLonicera japonica Thunb. could be obtained by means of decoloration with S8 macroporous adsorptive resins..
