桑叶中1-脱氧野尻霉素提取的工艺研究

Study on the extraction technology of 1-from the mulberry leaves

利用单因素试验和正交试验研究酸水提取法桑叶中DNJ的提取工艺。确定最佳工艺条件为:桑叶粉末粒度60目、提取温度55℃、pH3盐酸溶液、料液比为1:20(g/m L)、提取时间为60 min。

The extraction process of DNJ in mulberry leaves in the single factor and orthogonal experiments acidic water extraction method. The optimum conditions were as follows： mulberry leaf powder size of 60 mesh, extraction temperature of 55℃ and pH3 hydrochloric acid solution,solid to liquid ratio is 1： 20 （g/mL）, the extraction time is 60 min.
