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℃.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
