Abstract

Paralytic toxicity was detected by tetrodotoxin (TTX) bioassay in all 15 specimens of the xanthid crab Lophozozymus pictor collected from northern Taiwan in 1993. The average toxicity of crab specimens was 921 +/- 231 (mean +/- S.E.) mouse units. The toxin of crab was partially purified and then identified. It was found that the crab toxin contained TTX and gonyautoxin. The ratio of TTX to gonyautoxin for crab toxin was about 9:1.

摘要

1993年从台湾北部采集的15只黄斑蟹（Lophozozymus pictor）样本，通过河豚毒素（TTX）生物测定法均检测出麻痹性毒性。蟹样本的平均毒性为921±231（平均值±标准误）小鼠单位。对蟹毒素进行了部分纯化，然后进行鉴定。发现蟹毒素含有河豚毒素和石房蛤毒素。蟹毒素中河豚毒素与石房蛤毒素的比例约为9:1。
