山核桃外果皮中核桃酮热回流法提取的工艺条件

摘要

为了更好地利用山核桃资源,提高产品的附加值,以山核桃外果皮中核桃酮的提取量为指标,采用单因素试验设计与正交试验法L_9(3~4),就热回流法提取的工艺条件进行了试验研究.结果表明,最佳的热回流法提取工艺条件为:以95%的乙醇为最佳提取溶剂,提取2次;提取温度为80℃,固液比为1∶10,回流时间为60 min.此提取工艺简单可行、稳定可靠,适用于核桃酮的大规模提取.%In order to make better use of Carya cathayensis resources and improve product value-added, the extraction of regiolone in epicarps was studied by hot-reflux method. On the basis of single factor experiment, the results indicated that 95 ％ ethanol was the preferred solvent for regiolone extraction and extract twice enough. The optimum conditions of orthogonal experiment were as follows: temperature 80 ℃, solid and liquid ratio 1 : 10, extracting time 60 min. The extraction technology for regiolone was scientific, rational and could be used in industrial production.
