Methods: from prepation of crude drug as start, study the technology of extract and defat with L9 (3~4) orthogonal test. With EtOH extraction and water sed, alkali washing, EtOAC extraction as main methods of eliminate dopant. Finally with alky AlzO3 chromatographic column, rich and gain anticancer active site. The maximum response was achieved at a 40 min extracting time with 10 times volume 90% EtOH added to the sample for the first time and 30 min for the second time. Adding 10 times water will produce precipitation; Place the precipitation into 6 times petroleum benzin to de-fat at 60℃.
