Objective: To reveal the effect of the crude phenolic, alkaloid and terpenoid compounds extracts of Lactuca serriola L. on some Human Pathogenic Bacteria.Methods: Antibacterial activities of the crude Phenolic, Alkaloid and Terpenoid of medicinal plant were determined by in vitro by agar diffusion-method against some human pathogenic bacteria.Results: obtained results showed that among nine pathogenic bacteria, only Staphylococcus aureus and Staphylococcus saprophyticus Gram-positive were susceptible for Terpenoid, Alkaloid and Phenolic compounds while Staphylococcus epidermidis was resistant to active compounds.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.
