Seven microcystins from Microcystis waterbloom in Lake Dalai,China

Seven types of microcystins,isolated from Microcystis waterbloom in Lake Dalai,were characterized.The major toxins:MCYST-LR,MCYST-RR,[D-Asp3]MCYST-LR and[Dha7]MCYST-LR were identified by high performance liquid chromatography（HPLC）,as com-pared with the authentic microcystins.The minor toxins:MCYST...

Zusammenfassung:	Seven types of microcystins,isolated from Microcystis waterbloom in Lake Dalai,were characterized.The major toxins:MCYST-LR,MCYST-RR,[D-Asp3]MCYST-LR and[Dha7]MCYST-LR were identified by high performance liquid chromatography（HPLC）,as com-pared with the authentic microcystins.The minor toxins:MCYST FR,[L-Mser7]MCYST-LRand an unknown MCYST which was most likely to be MCYST-（H4）YR were identified with frit-fast atom bombardment liquid chromatography/mass spectrometry（Frit-FAB LC/MS）and aminoacid analysis.The toxigenic diversity in blue-green algae（cyanobacteria）was discussed.
