| 摘 要： | 以脱色率和多糖保留率为指标，采用活性炭和大孔吸附树脂两种方法对车前草多糖脱色。结果表明，活性炭脱色的最佳条件为：在60℃下，加入0．75％（m／V）的活性炭，脱色30min，在此工艺条件下脱色率为76．22％，多糖保留率为65．31％。大孔吸附树脂脱色的最佳条件是：以蒸馏水为洗脱剂，样pH值为8．0，洗脱流速为2mL／min，洗脱液体积为3BV（1BV=20mL），在此工艺条件下脱色率为79．78％，多糖保留率为89．76％。大孔吸附树脂脱色效果优于活性炭脱色效果。

| Abstract: | The decoloring methods with active carbon and AB-8 macroporous adsorption resin were compared for polysaccharide extracted from Plantago asiatica L was decolored by analyzing the decoloration rate and polysaccharide retention rate. The results showed that the best conditions for decoloration with active carbon were： 0.75% active carbon, decoloring temperature 60℃ and treatment time 30min, under which the decolorization rate was 76.22% and the polysaccharide retention rate was 65.31%. The best conditions for AB-8 macroporous adsorption resin were as follows： the elution solvent 3 BV （1 BV=20 mL）, flow rate 2 mL/min, and pH of polysaccharide solution 8.0, under which the decolorization rate was 79.78% and the polysaccharide retention rate was 89.76%. The decoloration with macroporous adsorption resin was better than that with active carbon. |
