Abstract:

       1HNMR can be employed to determine the molecular structures of bile acid and its derivatives. This paper studies addresses the effects of methylacrylate on chemical shift of hydrogen on bile acid steroids skeleton. Results show that chemical shift of hydrogen alters in order with methylacrylates substituting hydroxyl group hydrogen atoms of bile acid one by one.

Key words: 1HNMR, chemical shift, bile derivatives, hydrogen
