title: [Ti-AI intermetallic compound membrane refining Chinese medicinal materials extract].
abstract: OBJECTIVE
  To preliminarily evaluate the refining effect on Chinese medicinal materials extract using the microfiltration membrane of Ti-A1 intermetallic compound.
  
  
  METHODS
  Conduct a series of microfiltration experiments on the extract of several commonly used Chinese medicinal materials (Nelumubinis Plumula and Eucommiae Folium)and compound preparation of Baihuasandi. Then, analyze the changes of traits, total solid and index components before and after filtring.
  
  
  RESULTS
  After two stages (10 microm and 30 microm) of membrane micro-filtring, the total solid removal rates of Nelumubinis Plumula were 1.2% and 22.66%, and the remaining rates of neferine were 97.56% and 95.12%; The total solid removal rates of Eucommiae Folium were 1.2% and 22.66%, and the remaining rates of caffeotannic acid were 95.50% and 87.28%; The totalsolid removal rates of Baihuasandi were 11.09% and 14.29%, and the remaining rates of quercetin were 98.58% and 95.43%, respectively.
  
  
  CONCLUSIONS
  Microfiltration membrane technique utilizing the Ti-Al intermetallic compound has a good effect in refining Chinese medicinal materials extract.
