SUMMARY Nineteen compounds isolated from field samples of cyanobacteria Woronichinia naegeliana (Unger) Elenkin were identified. They fell into four classes of peptides: cyanopeptolins (cyanopeptolin B, cyanopeptolin C, cyanopeptolin D, cyanopeptolin 880, micropeptin 88D, micropeptin 478‐B, micropeptin SD999, micropeptin T2, planktopeptin BL1061), microginins (microginin 478, microginin 757, microginin 51A, microginin 91E, microginin FR3, microginin FR4), anabaenopeptins (oscillamide B) and possibly microcystins (trace amounts of microcystin‐LR) showing respectively fragment patterns in their electrospray ion source‐MS spectra. The molecular masses of the determined peptides range from 700 to 1100 Da. These results confirm the remarkable ability of cyanobacteria to synthesize a wide array of peptides.
