Abstract
Various microcystins (MCs) were isolated from extracts of Microcystis aerug inosa grown in lake Thong Cong, Hanoi,Vietnam. MC-RR, MC-YR, and MC-WR were determined by liquid chromatography with mass spectrometric detection (LC-MS). Besides these major microcystins five mino r compounds were identified as microcystins using fragmentation mass spectr ometry (LC-MS-MS). Two minor compounds were identified as desmethyl variant s of MC-WR and MC-RR respectively, and a third as an MC-LR variant. Two com ponents showed characteristic fragmentation profiles of MC but could not be characterised exactly owing to their low concentrations. Three othercompon ents (900 - 1100 dalton) proved not to be microcystins.
