| Abstract: | The pollution of freshwater lakes caused by algal blooms which can release the mieroeystins （MCs） became serious in recent years. The separation and characterization of MCs isomers are very important to the research of water supply security. MCs isomers were extracted from eyanobacteria of Dianchi Lake and separated by high performance liquid chromatography. Different ratio of extract solvent and chromatographic conditions were discussed. Five MCs isomers were successfully extracted. Three of which were characterized by HPLC - MS. |
