柱层析法分离制备冬凌草甲素的新工艺

The New Method for Preparing Oridonin by Column Chromatography

采用柱层析法分离制备冬凌草甲素，与原工艺相比，具有洗脱速度快，溶剂无毒无污染，安全、价廉、易得等优点。经重结晶后用薄层扫描法测定含量达９７０３％。

Compared with the traditional methods,the separation and preparation of oridonin by column chromatography have the advantages of fast speed,harmlessness and non pollution of solvent,safety,economy and easily obtained,etc.After re crystallizing the oridonin content is determined by TLC scanning to be as high as 97.03%.
