Popis:	1. 1. Homogenates of total body extracts of the brine shrimp (Artemia sp.) were analysed for the presence of pregnenolone and estradiol by gas chromatography followed by mass spectrometry. 2. 2. Selected ion monitoring analyses revealed that the molecular ion and two characteristics fragment ions of pregnenolone, and the molecular ion with its isotopes and four characteristic fragment ions of estradiol were present at the proper retention times and with the correct abundance ratios.
