The toxins of xanthid crab Atergatis floridus from Chiba were purified successively on activated charcoal, Bio-Gel P-2, and Bio-Rex 70, and then analyzed by thin layer chromatography and electrophoresis. No significant different difference was observed between August and November specimens. In Bio-Rex 70 column chromatography, 99% of the toxins were eluted with 0-0.03 and 1% with1.5N acetiacid; these results indicated that the crabs in Chiba contain gonyautoxins as major toxic components, differing from those in okinawa in which saxitoxin and neosaxitoxin are predominant. three toxins, none of which were in accord with the standards used, were detected in the gonyautoxin fraction. One of them was the major toxic component, since its relative ratio to the total toxicity was as high as 85-91%.
