Abstract
Paralytic toxicity was detected by tetrodotoxin (TTX) bioassay in all 15 specimens of the xanthid crab Lophozozymus pictor collected from no rthern Taiwan in 1993. The average toxicity of crab specimens was 921 +/- 231 (mean +/- S.E.) mouse units. The toxin of crab was partially p urified and then identified. It was found that the crab toxin containe d TTX and gonyautoxin. The ratio of TTX to gonyautoxin for crab toxin was about 9:1.
