Abstract
Blue-green algae (cyanobacteria) in tablets and capsules, which are marketed as health food supplements, were investigated for the presence of neurotoxins related to anatoxin-a. These neurotoxins, which are nicotinic agonists, were investigated using isocratic micro-liquid chromatography-tandem mass spectrometry (micro-LC-MS-MS). The investigated compounds were anatoxin-a and homoanatoxin-a, together with their degradation products, dihydroanatoxin-a, epoxyanatoxin-a, dihydrohomoanatoxin-a and epoxyhomoanatoxin-a which were synthesized from the parent toxins. The analytes were extracted with methanol followed by isocratic chromatography on a micro C18Keywords
