Tetrodotoxins (TTXs) were investigated in two local pufferfish species, Diodon hystrix and Arothron hispidus, from Mozambican coast. TTX and analogues 4-epiTTX, 4,9-anhydroTTX, 11-deoxyTTX, and 11-norTTX-6-(R/S)-ol were found in both species and high level of TTX was found in A. hispidus (9522.0 μg TTX kg) than in D. hystrix (350.9 μg TTX kg). The distribution of TTX and their analogues in A. hispidus was intestine > liver > skin ≫ muscle > gonads. This is the first report of TTXs in Mozambican coast.
在来自莫桑比克沿海的两种本地河豚鱼，Diodon hystrix 和 Arothron hispidus 中研究了河豚毒素 (TTXs)。在这两种鱼中都发现了 TTX 和类似物 4-表 TTX、4,9-脱水 TTX、11-去氧 TTX 和 11-去甲 TTX-6-(R/S)-醇，并且在 A. hispidus 中发现了高水平的 TTX（9522.0μg TTX kg），而在 D. hystrix 中则发现了较低水平的 TTX（350.9μg TTX kg）。TTX 及其类似物在 A. hispidus 中的分布为肠道>肝脏>皮肤>肌肉>性腺。这是莫桑比克沿海地区首次报告 TTXs 的存在。
