摘　　要：采用螯合剂辅助提取核桃青皮原花色素,通过单因素试验和正交试验设计进行工艺参数优化。结果表明,最佳提取工艺条件为乙醇体积分数40%,提取温度50℃,提取时间80 min,EDTA质量分数0.1%。在此条件下,核桃青皮原花色素的提取率为31.992 mg/100 g。Walnut green husk is used as material to extract proanthocyanidins by ethanol extraction with chelating agent. On the basis of single-factor experiments, the optimum extract condition of proanthocyanidins from walnut green husk is set up by orthogonal test. The results show that the optimal parameters for the extraction are 40% ethanol, temperature 50℃, time of extraction 80 min, 0.1% EDTA. Under the conditions, proanthocyanidins extraction rate is 31.992 mg/100 g.
