摘　　要： 选择大孔吸附树脂法和高速逆流色谱法对虎杖中白藜芦醇进行分离纯化。通过实验条件的优化以及对两种方法的比较发现:经大孔吸附树脂法分离纯化所得的白藜芦醇得率稍高,为0.21%,但纯度偏低,仅为51%;经高速逆流色谱法分离纯化所得的白藜芦醇得率稍低,为0.186%,但纯度大于96%,远远高于大孔吸附树脂法所得。 In this paper,two methods are selected to separate and purify of the resveratrol from Polygonum cuspidatum,macroporous adsorption resin method and HSCCC method.Through the optimization of experimental condition and the comparison of two methods,the results are as follows: The resveratrol yield is slightly higher by the macroporous adsorption resin purification,it is 0.21%,while the purity is low,only 51%; the resveratrol yield is slightly lower by the HSCCC method,and it is 0.186%.However,the purity by HSCCC is over 96%,which is much higher than macroporous adsorption resin purification.
