To reveal the effect of the crude phenolic, alkaloid and terpenoid
compounds extracts of Lepidium sativum L on some Human Pathogenic Bacteria.
Methods: Antibacterial activities of the crude Phenolic, Alkaloid and Terpenoid of medicinal
plant were determined in vitro by agar well diffusion-method against some human pathogenic
bacteria.
Results: obtained results showed that active compounds of Lepidium sativum L had wide
spectrum antibacterial activity against gram-positive and gram-negative bacteria.
Conclusion: This study demonstrates that we can conclude that the effect of active compounds
in same plant has different effect on different pathogenic organisms in different concentration
