It is not often that three misconceptions are associated with one molecule for more than a century. This is the case with adrenaline. The aim here is to clarify that adrenaline was the first hormone, with the discovery of its activity and chemical purification being prior to secretin. Adrenaline is the correct name given by Jōkichi Takamine, epinephrine being its inactive benzoyl derivative.

第一种激素：肾上腺素

一个多世纪以来，三个误解与一个分子相关联的情况并不常见。肾上腺素就是这种情况。这里的目的是澄清肾上腺素是第一种激素，其活性和化学纯化的发现先于促胰液素。肾上腺素是 Jōkichi Takamine 给出的正确名称，肾上腺素是其无活性的苯甲酰衍生物。
