الملخص EN

An alkaloid piperine was extracted from dry seeds of plant Piper nigrum with ethanol by using saxohlet extraction then isolation and purification by re- crystallization , the structure of Piperine was confirmed by the IR spectroscopy.

Antimicrobial activity of Piperine was studied against gram+ve, gram-ve bacteria and Candida albicans piperine showed potent antimicrobial activity against tested organisms especially C.

albicans followed by E.
