Abstract
Abstract 2-Deoxy-20-hydroxyecdysone was identified in the ovaries of pharate adults of the silkworm, Bombyx mori, by mass spectrometry and high performance liquid chromatography. Together with 2-deoxyecdysone, 2,22-bisdeoxy-20-hydroxy-ecdysone and ecdysone, this ecdysteroid constitutes one of the four major moulting hormones of Bombyx mori ovaries. Accumulation in ovary of these ecdysteroids suggests a forked pathway of biosynthesis, one leading to ecdysone and the other to 20-hydroxyecdysone.
