Methods The compounds were isolated by silicagel, ODS, and macroporous resin column chromatography and their structures were determined by means of spectral analysis.
方法利用正相、反相硅胶柱和大孔树脂柱色谱分离，并通过波谱技术进行结构鉴定。

Methods Silicagel superfine process was conducted by combining solvent extraction and separation with macroporous absorbent resin.
方法首先用溶剂萃取结合大孔吸附树脂分离，然后用硅胶柱精制提取。
