肉豆蔻对照品去氢二异丁香酚制备工艺
摘要
目的:优化制备去氢二异丁香酚中药化学对照品的工艺。方法:以去氢二异丁香酚提取率为考察指标
在单因素试验的基础上
通过L9(34)正交试验确定最佳提取条件并放大到中试量。结果:采用80%乙醇
料液比10∶1回流提取药材2次
每次2 h
提取物经无水乙醇、乙酸乙酯萃取后
经硅胶柱层析、重结晶
获得9 g对照品。结论:本工艺高效、简便、低成本
适用于去氢二异丁香酚对照品的制备。
Abstract
Objective:To optimize the process of preparing dehydrodiisoeugenol chemical reference substance.Method:Taking extract rate of dehydrodiisoeugenol as index
the best extraction condition of dehydrodiisoeug-enol was determined by single factor test and orthogonal test L9(34)
which was scaled up to pilot volume.Result:Raw material was extracted with 80% ethanol at a 10∶1 solid-liquid ratio for twice and 2 h each time
the yielded extract was first seperated by extraction with absolute ethyl alcohol、acetyl acetate.Afer this
by the methods of silicagel column chromatography and recrystallization we produce 9 g of reference substance was producued.Conclusion:The process is effective
