Methods: Liquid-liquid partition, solid-phase separation extraction. silica-gel chromatography, Al2O3 chromatography and thin-layer chromatography were performed and compared for separation of paclitaxel. 采用液-液萃取、固相萃取、硅胶柱层析、氧化铝柱层析、薄层层析五种分离方法对紫杉醇进行了初分离。
Multilayer coil planet centrifuge, also called high-speed countercurrent chromatography ( HSCCC), is a new type of liquid-liquid partition chromatography. 多层螺旋管行星式离心仪又称高速逆流色谱仪,是一种新型的液液分配色谱技术。
