Determination of unconjugated neurosteroids in rat brain regions by liquid chromatography-negative atmospheric pressure ionization mass spectrometry
To simultaneously determine three unconjugated neurosteroids, dehydroepiandrosterone (DHEA) , pregnenolone (PREG), allopregnenolone (AP), from several brain regions of the rat. Neurosteroids were isolated separately in a two steps procedure by using ethyl acetate-n-hexane (90:10) as the first step t...
