title: Occurrence of tetrodotoxin in the flatworm Planocera multitentaculata.
abstract: The paralytic toxin which occurs in a flatworm Planocera multitentaculata was partially purified by column chromatography using Bio-Gel P-2 and Bio-Rex 70 (H+ form). Thin-layer chromatographic, electrophoretic and gas chromatography-mass spectrometric analyses demonstrated that the flatworm toxin is tetrodotoxin.
