Abstract:  Research has been carried out on the technology of separating resveratrol and procyanidin extracted from the peanuts red skin. The macroporous adsorption resin AB-8 have been selected from 3 kinds of carriers by static adsorption and de-adsorption test. The single factor tests and orthogonal experiments have been applied to optimize the enrichment and separation condition of resveratrol and procyanidin. The optimum adsorption conditions were as follows: feeding rate 1ml/min, pH value 7.0 with the concentrations of resveratrol and procyanidin to be respectively 2μg/ml and 0.6mg/ml. The optimum elution conditions were elution rate 1.5ml/min and pH value 5.0. Resveratrol and procyanidin could be purified and separated by different concentration of methanol. Resveratrol was eluted by 20% methanol while procyanidin by 40% and 60%. After combining the same components, the products could be obtained by concentration and lyophilization with the contents of resveratrol and procyanidin as respectively 43.6%  and 93.05%.
