摘　　要：采用浸取法、微波提取法、超声波法研究黄连中的抗氧化性物质,通过测定吸光度利用Fenton反应表征提取物对羟自由基的清除率,通过正交实验对提取黄连素的工艺条件进行优化。实验表明:最佳提取方法是微波提取法,蒸馏水为溶剂,料液比为1g∶60mL,微波功率为40 W,处理时间为4min时清除率最高。The ordinary extraction method, microwave extraction method and ultrasonic method were used to extract antioxidant substances in coptidis, and the obsorbance of hydroxyl radicals was tested using Fen- ton reaction. The best extraction conditions were obtaind by orthogonal experiment. The results showed that the best extraction method was microwave extraction method, and the optimal treatment conditions were： solid-liquid ratio of 1 g ： 60 mL, distilled water as solvent, microwave power of 40 W and the pro- cessing time of 4 min.
