Puffer fish poisonous already known. Why is puffer poisonous? The late nineteenth century, Japanese scholars began to study. It was not until the 1950s that the tetratrodotoxin was successfully isolated from puffer ovary. (Abbreviation TTX). 1964 elucidated its structure. Fully synthesized in 1972 to be successful. First, separation and purification Now Hirata et al improved separation process as shown below:
