Purification of Natural Compounds      

 With a flash chromatography system (Alltech Associates Incorporation), a preparative LC-MS system (Waters) and a semi-preparative SFC-MS system (Waters), the research group has the advanced technology to isolate and purify natural compounds in a fast and effective way. The isolated compounds can be identified by LC-NMR and LC-MS and their bioactivity can be tested in in vitro or in vivo test systems.
