Abstract

Paralytic toxicity was detected by tetrodotoxin (TTX) bioassay in four and five specimens of new toxic xanthid crab Xanthia lividus collected from Lanyu, south-east Taiwan in April 1999 and Hsiaoliuchiu south-west Taiwan in November 1999, respectively. The average toxicity of crab specimens collected from Lanyu and Hsiaoliuchiu was 230±94 (mean±SD) mouse units (MU) and 241±114 MU, respectively. The toxin was partially purified by YM-1 membrane ultrafiltration and Bio-Gel P-2 column chromatography. Electrophoresis, high-performance liquid chromatography and gas chromatography-mass spectroscopy analyses showed that the crab toxin was composed mainly of tetrodotoxin (83%), as well as a small amount of gonyautoxin 1-4 (17%).
