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 (1)H, (13)C, and (31)P nuclear magnetic resonance as the 22-N(6)-(isopentenyl)-adenosine monophosphoric ester of ecdysone.
新产下的昆虫蝗虫卵中含有高浓度的母体来源的蜕皮激素缀合物（每克 50 毫摩尔）；通过常规技术分离出 3 毫克这种缀合物，并通过质谱和（1）H、（13）C 和（31）P 核磁共振确定其结构为蜕皮激素的 22-N(6)-(异戊烯基)-腺苷一磷酸酯。
