| 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。 |
| 关 键 词： | 白藜芦醇 大孔吸附树脂 虎杖 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 1 ml/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. |
| Keywords: | resveratrol macroporous adsorption resin polygonum cuspidatum purification |
