摘　　要：用吸附树脂D4020和活性炭层析柱来分离纯化低聚木糖,将去离子水作为大孔吸附树脂的洗脱液,去离子水和体积分数30%的乙醇溶液作为活性炭的洗脱液。大孔吸附树脂D4020可以除去糖液38%的色素,但是它对低聚木糖的吸附力较小。通过活性炭柱层析可以得到以木二糖为主的低聚木糖产品。Xylooligosaccharides was isolated and purified with D4020 absorbent resin by elution with water and activated charcoal columns by elution with water and 30% ethanol. 38% of the pigment in the liquid was removed by the D4020 resin column, with a small absorbent capacity for xylooligosaccharides. The xylooligosaccharides liquid with xylobiose as major component was obtained by the activated charcoal column.
