中文摘要:
      以石油醚为提取溶剂，研究溶剂法提取酸枣仁油工艺。以提取时间、提取温度、料液比为影响因素，在单因素试验的基础上，以酸枣仁油得率为响应值，进行三因素三水平的Box-Behnken响应面法优化试验。结果表明：酸枣仁油最优提取工艺条件为提取时间6.9 h、提取温度 82.6?℃、料液比1∶?16.5，在此条件下，酸枣仁油得率达到32.21%，与模型预测值32.26%接近。
英文摘要:
      With petroleum ether as extraction solvent, the extraction of Ziziphi Spinosae Semen oil was studied by solvent method. With extraction time, extraction temperature and ratio of material to liquid as influencing factors, yield of Ziziphi Spinosae Semen oil as response value, three factors and three levels of Box-Behnken response surface methodology was conducted on the basis of single factor experiment. The results showed that the optimal extraction conditions of Ziziphi Spinosae Semen oil were obtained as follows: extraction time 6.9 h, extraction temperature 82.6?℃ and ratio of material to liquid 1∶?16.5. Under these conditions, the yield of Ziziphi Spinosae Semen oil reached 32.21%, close to 32.26% of predictive value.
