The medicinal value of the plants is due to their chemical components that bring a definite physiological action on the human body to prevent the diseases. In this work, we investigated the antimicrobial activity of leaves’ extracts of Quercus robur L., collected from the Algerian upper highlands, on ten bacterial strains and one fungal strain known to be pathogenic. First, we performed a qualitative phytochemical analysis, and second, antimicrobial activity tests performed by agar diffusion method (disc and well) with the determination of MIC by broth macro-dilution method. Given the results, it appears that obtained macerates of Quercus robur L. were rich in bioactive phytoconstituents such as alkaloids, anthraquinones, saponins, tannins, and other components. The yield of aqueous and methanolic macerates of leaves was 8.5 ± 1.41 and 22.4 ± 4.36%, respectively. The bacterial resistance was relatively important to several antibiotics, namely, ampicillin, amoxicillin + clavulanic acid for strains of Escherichia coli and Salmonella sp. However, Staphylococcus aureus strains were resistant to fusidic acid, penicillin, and oxacillin; while Enterococcus faecalis was resistant to fusidic acid, penicillin, oxacillin, and ticarcillin. The antibacterial activity of the macerates toward tested microbial strains showed that the aqueous and methanolic macerates of the leaves were proportional to the tested concentration and active not only against Gram-positive and Gram-negative bacteria but also on the fungal species Candida albicans. The estimated MIC for Escherichia coli, Enterococcus faecalis, and Staphylococcus aureus was in the order of 10 mg/mL, which seems more effective than toward Salmonella sp., Klebsiella pneumoniae, Pseudomonas aeruginosa, and Candida albicans which were in the order of 30 mg/mL. These preliminary results confirm that the part of the studied plant had a very good antimicrobial activity that was proportional to the serial concentrations of the tested extracts.

Comparative study of plant extracts crude and aqueous, methanolic and ethanolic with antibiotics, provide evidence that calotropis procera extracts has the similar antibacterial activity as these antibiotics against test pathogens i.e. Salmonella typhi and E.coli. The analysis of antimicrobial activity of aqueous, methanolic and ethanolic extract of leaves and flower of Calotropis procera was carried out in disc method and also determined MIC value at 600nm through optical density using spectrophotometer. The zone of inhibition produced by extracts was examined and compares it with zone produced by antibiotics. The effect exhibited by ethanolic extract of leaves and flower was significantly greater than the aqueous and methanolic extract of leaves and flower. Crude extracts i.e. latex, leaves, fruit and flower crude extracts. Among them, flower crude extracts shows similar zone of inhibition to test anitibiotics.while in MIC value, we made different concentration of extracts and antibiotics.i.e for crude we made 25%, 50%.75% and 100% concentration of crude juice and for the aqueous, methanolic and ethanolic we made 0.5mg/mL,1mg/mL,2mg/mL,3mg/mL,4mg/mL, 5mg/mL and 6mg/mL in Dimethyl salfoxide, and same antibiotics concentration. Aqueous leaves extracts show MIC at 0.5mg/ml against E.coli while against Salmonella it shows MIC at 1mg/ml... We also determine phytochemical analysis for presences of different compounds in crude extracts. The obtained results provide a support for the use of Calotropis procera, in traditional medicine and suggest its further advance investigation.
