Newly laid eggs of the insect Locusta migratoria contain high concentrations (50 nanomoles per gram) of an ecdysone conjugate of maternal origin; 3 milligrams of this conjugate were isolated by conventional techniques, and the structure was established by mass spectrometry and 1H, 13C, and 31P nuclear magnetic resonance as the 22-N6-(isopentenyl)-adenosine monophosphoric ester of ecdysone.
