Synthesis, Characterization of Some Derivative Piperic Acid, Which Extraction from Black Pepper.

Abstract

Piperic acid was extracted from black pepper by ethanol as asolvent, then it reacted with solution of bromine in carbon tetra chloride to make tetra bromine derivative. Also the acide reacted with bromine water solution to make bromohydren derivative which cyclzation occurs in presence of sodium hydroxide solution to form epoxide derivative. This cycle will opend with aniline derivative to synthesid some derivative amino alcohole for acid. The structure of syntheside compounds have been established by using IR and UV. Visible, melting point and TLC. The biological activities are studied against four different kinds of bacteria .
