摘　　要：以胡桃楸青果皮为试材,通过单因素试验优选了青果皮青龙衣中胡桃醌的最佳提取方法和最佳提取溶剂,并用正交法验证了料液比、提取时间和提取温度对胡桃醌提取率的影响。结果表明:以乙酸乙酯为提取溶剂,冷浸法结合超声法提取胡桃醌的提取效果最佳;各因素对提取率的影响顺序为固液比>提取时间>提取温度;最佳提取工艺为料液比1∶20g/mL,提取时间为40min,提取温度为25℃。Taking Juglans mandshurica green husks as test materials, the best methods to extract juglone and best extraction solvent were optimized by single factor test, and the influence of solid-liquid ratio, extraction time and temperature on extraction rates was verified through orthogonal test. The results showed that ethyl acetate was the best extraction solvent, co｜d soak method combined with ultrasonic was the optimum extraction method;the order of factors on the extraction rate of juglone was： solid-liquid ratio extraction time.extraction temperature; the best extraction technology was：solid-liquid ratio 1 ： 20 g/mL,extraction time 40 min,extraction temperature 25℃.
