Extraction and Detection of Microcystin-LR from Microcystic Aeruginosa

The extraction and purification of microcystin from microcystic aeruginosa were studied. The efficiency for microcystin extraction was assessed by comparing different polarity extraction agents. Results showed that 60% methanol has the highest efficiency. Ethanol solution could extract microcystins safely, and can be used as a massive security extraction agent. The extraction method and solid phase extraction measure were improved, and suitable flowing phase composition was chosen to detect microcystin-LR.
