| Abstract: | A toxin isolated from waterbloom of the colonial cyanobacterium %Microcystis aeruginosa% collected in a fish pond was studied by one dimensional and two dimensional nuclear magnetic resonance techniques. Combined with other analytical techniques, it is shown that this toxin is just microcystin LR, the most common cyclo heptapeptide. The connectivity of amino acids in the cyclic part of this toxin is determined. ; |
