Sodefrin, a novel decapeptide which attracts female newts, Cynops pyrrhogaster was isolated from the abdominal gland of the male of the same species. Synthetic sodefrin was tested for its activity with sexually active females and males and sexually inert females. It attracted only sexually active females. The effect of sodefrin was blocked by a bilateral nostril plugging with cotton balls soaked in melted vaseline. Immunoelectronmicroscopic study using antiserum against sodefrin revealed that sodefrin was located mainly in the secretory granules in the epithelial cells of the abdominal gland of the cloaca.
索德蛙素是一种从同物种雄性腹腺中分离出的新型十肽，它能吸引雌性日本红腹蝾螈。对合成的索德蛙素进行了活性测试，测试对象包括性活跃的雌性和雄性以及性不活跃的雌性。它只吸引性活跃的雌性。用浸有熔化凡士林的棉球双侧堵塞鼻孔可阻断索德蛙素的作用。使用抗索德蛙素抗血清进行的免疫电子显微镜研究表明，索德蛙素主要位于泄殖腔腹腺上皮细胞的分泌颗粒中。
