The natural-abundance 13C nuclear magnetic resonance spectra of certain phytoecdysones and their selected derivatives have been measured at 25 MHz. With the aid of complete noise, off-resonance, and single-frequency proton decoupling techniques, and the shifts which occur on formation of specific derivatives, it has been possible to make assignments of the resonances for the phytoecdysones.
