The antimicrobial effect of the artimisa herba and erodium glaucophyllum against pathogenic bacteria

الملخص EN

Artimisa herba and Erodium antimicrobial activity were used against Serratia spp., Bacillus cereus, E.coli, Micrococcus roseus, Staphylococcus aureus, Streptomyces spp.

and Micrococcus lutaus.

The method of extraction applied in this paper was the Soxhlet- hot extraction using petroleum ether and alcoholic solvents.

The bacterial inhibition by the extract was as follows: Serratia spp was found moderately sensitive to Artimisa herbawith failure to produce pigment.

B.

cereus was found moderately so to Artimisa herba while it showed low response to.

Erodium glaucophyllum.

Escherchia coli showed moderate inhibition to Artimisa herba, Micrococcus roseus responded well to and grodium moderately to grodium.

Staphylococcus aureus responded well to moderately to Artimisa herba.

Streptomyces spp.

responded well only to based on the results obtained in this study, it can be concluded that using 50% acetone extract of, Erodium glycophyllum has high antibacterial activity against pathogenic Staphylococcus aureus.

Hot Soxhlet extraction method is recommended as well as 96 well treys microtitre plate method.

The MIC of tested Erodium glycobhyllum against Staphylococcus aureus was 25 and 50 mg/ml, respectively.

Peganum showed moderate response to Eoridium Micrococcus luteaus showed height to moderate response to Erodium, However the exception of Erodium in high concentration, None of the tested plants showed any signs of toxicity in rats tested.

The former produced liver fatty changes and haemorrhages in the kidneys.

Toxicity experiments of Erodium glycophyllum, and Artimisa herba using experimental animals (rats) confirm the safety of such plants for therapy of various diseases.

An antibacterial Evaluation for the total extract of tested medicinal plants could also reveal a more potent activity toward tested pathogenic Gram positive and Gram negative bacteria.

However, the plants differed significantly in the activity towards tested pathogenic bacteria.

The differences could be attributed to their structural nature.
