摘　　要：山杏核壳是生产中的下脚料,开发利用较少。以山杏核壳为原料提取黑色素,通过响应面法优化工艺条件。在单因素实验基础上选取实验因素与水平,根据Box-Benhnken中心组合实验设计原理采用四因素三水平的响应面分析法。得到最佳提取工艺为:料液比1:20,温度60℃,碱液浓度1mol/L,时间4h;在此条件下,提取得率可达8.33%。With less utilization, core-shell of wild apricot was the scarps of production. On the basis of single factor experiments,the optimum conditions for the extraction of the melanin from core-shell of wild apricot were obtained through Box-Benhnken center-united experiment design and response surface methodology.The results showed that the optimum conditions of extraction of the melanin from core-shell of wild apricot were as follows： liquid ratio 1：20, temperature 60℃,alkali concentration tmol/L,time 4h.Under this condition,the maximal yield of melanin was up to 8.33%.
