A partition assay is described which allows a rapid determination of juvenile hormone release by insect corpora allata. Newly synthesized and released methyl-labeled C,, juvenile hormone is quantitatively extracted into an isooctane phase, whereas precursor methyl-labeled L-methionine remains in the

β¦ Synopsis
Corpora allata incubated in appropriate medium release several compounds including juvenile hormones. Juvenile hormones (14C labeled or unlabeled) were extracted with hexane and directly analyzed by gas chromatography-mass spectroscopy. This method allowed the qualitative and quantitative analysis of total released juvenile hormone. It could also be used as a routine assay for evaluation of corpus allatum activity. Data obtained by this method were compared to those obtained by radiochemical assay.
