层析分离技术

针对上述问题，本文首次将超临界CO2萃取与柱层析分离技术联合应用于ORI的提取与分离，使ORI的制备工艺大大简化，对推动ORI向工业化生产方向发展具有重要意义。

In order to solve the problems mentioned above , we established a novel method for the extraction and separation of oridonin , which combined the supercritical CO_2 fluid extraction technology to the column chromatography technology .

方法：应用硅胶柱层析等分离技术分离化合物，根据理化性质及IR，MS，NMR等光谱数据鉴定结构。

METHOD : By way of spectra as IR , MS and NMR .
