摘要: 利用大孔吸附树脂分离纯化虎杖中的白藜芦醇。实验结果表明,NKA-9型大孔吸附树脂对白藜芦醇的吸附、解吸性能较好。在料液浓度3~4mg/ml,上柱速率1ml/min,上样量0.5BV,pH值为4的条件下吸附;解吸采用75%酒精,解吸流速1ml/min,pH值为8时可以将白藜芦醇较好的纯化。

Abstract: Resveratrol is purified by macroporous adsorption resin from polygonum cuspidatum .The experiment results show that a resin type of NKA-9 is better in adsorption and desorption to resveratrol. Resveratrol can be purified well under the condition of material concentration 3~4mg/ml, sample flow velocity 1ml/min, sample quantity 0.5BV, pH=4 for adsorption; 75% ethanol as desorption solvent, desorption velocity of flow 1.0ml/min, pH=8 for desorption.

Key words: resveratrol, macroporous adsorption resin, polygonum cuspidatum, purification
