title: Gas chromatography-mass spectroscopy analysis of juvenile hormone released by insect corpora allata.
abstract: 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.
