    Abstract

    Tetrodotoxin (TTX) and its analogue 6-epiTTX were detected in 11-12 specimens of the red-spotted newt, Notophthalmus viridescens, by a post-column fluorescent-HPLC system and by LC/MS in selected ion monitoring mode. TTX levels varied considerably among individuals from low (less than 0.15 μg TTX/g newt) to high concentrations (23.5 μg TTX/g newt), while 6-epiTTX was found to be a minor constituent in all specimens.
