Product Application
Pregnenolone powder is used in biochemical research. It is an intermediate of hormone drug progesterone. It is used in the synthesis of steroid drug intermediates and steroid drugs.Pregnenolone is an important hormone in the human body. When the pregnenolone content in the body is unbalanced, it will have adverse effects on physical health. In this case, pregnenolone needs to be supplemented.
Rapid separation of gonadal steroids in the progesterone(Δ4) and pregnenolone pathway (Δ5) has been accomplished by the use of high performance liquid chromatography (HPLC). Two HPLC systems are utilized. The first requires the use of two separate radial compression columns (C-18 and C-8), with steroids being eluted with a methanol-water gradient. The second employs a stainless steel C-18 (reversed phase) column with a 12% octadecylsilane coating. The latter system separates seven of the eight steroids in the Δ4 and Δ5 pathways in thirty-five minutes.
For the quantitation of steroids directly, integration of the peak areas, using 254 nm absorption for the Δ4 pathway steroids (5 ng minimum limit), and 210 nm absorption for the Δ 5 pathway steroids (25 ng minimum limit) is used. For the quantitation of radiolabeled metabolites resulting from incubation of gonadal tissue with radiolabeled steroid precursors, either one of two methods is used: (1) the eluent can be recovered from the HPLC using a fraction collector, and counted in liquid scintillation counter or (2) the entire eluent (or a portion of it) can be counted immediately by directing the flow through a radioactivity detector.
