Adrenaline Determination by High Performance Liquid Chromatography

How to detect epinephrine by HPLC?

Adrenaline is a hormone and neurotransmitter released by the adrenal glands. Adrenaline will increase the contractility of the heart, dilate the blood vessels of the heart, liver, muscles and bones, and constrict the blood vessels of the skin and mucous membranes. It is a necessary product to save dying people or animals. Its biosynthesis is mainly to first form norepinephrine in medullary chromium cells, and then further through the action of phenylethanolamine N-methyl transferase (PNMT) to make norepinephrine methyl The formation of adrenaline.
