2,22-Dideoxy-23-Hydroxyecdysone and its 3-Phosphate from Ovaries of the Silkworm,<i>Bombyx mori</i>

Abstract

Abstract Two new ecdysteroids have been isolated from the mature ovaries of the silkworm, Bombyx mori. Their structures were established to be (23S)-2,22-dideoxy-23-hydroxyecdysone and its 3-phosphate on the basis of spectroscopic analysis including 1H-NMR comparison with the known compounds, 2-deoxy-ecdysone and (23R)-and (23S)-23,25-dihydroxycholesterols.
