“…The following zone diameter criteria were used to assign susceptibility or resistance of bacteria to the phytochemicals tested: Susceptible (S) ≥15 mm, Intermediate (I) = 11-14 mm, and Resistant (R) ≤10 mm (Okoth et al, 2013).…”

Purpose: To investigate the phenolic profile and biological activities of Argania spinosa L. leaves. Methods: The crude methanol extract of leaves of A. spinosa L. Skeels was obtained by ultrasonic extraction, and the total polyphenolic and flavonoid contents were determined by ultra-high performance liquid chromatography-electrospray ionization-quadrupole time-of-flight-mass spectrometry (UPLC-ESI-QTOF-MS). In vitro antioxidant activity was determined by 2,2-di-phenyl-1-picryl-hydrazil (DPPH) radical myrecitin-3-galactoside, myrecitin-3-gluctoside, myrecitin-3-xyloside, quercetin-3-galactoside, quercetin-3-glucoside, quercetin-3-arabinofuranoside, and quercetin-3-rhamnoside

“…The rich chemical diversity in plants has been reported to be a promising source of antibacterial compounds (Ishnava et al, 2012 andOkoth et al,2013), raising hopes of obtaining novel antibiotics that can aid the fight against drug resistant infections. Synergism due to combination of plant extracts with antibiotics help to minimize the minimum inhibitory concentrations (MICs), consequently reduce the side effects, economic cost, and reduce sensory impact.…”

A total of seventy-five medical specimens were collected from different patients admitted to Zagazig university hospital, Egypt. The selected bacterial isolates were distributed as 45 Gram negative bacterial isolates and 30 Gram positive bacterial isolates. The most effective antibiotic was gentamycin followed by amikacin and nitrofurantoin. The multi-drug resistant (MDR) bacterial isolates were selected and identified to four groups; Pseudomonas aeruginosa, Klebsiella pneumoniae, Escherichia coli and Staphylococcus aureus. The selected isolates were screened for their capability of biofilm, hemolysins, lecithinase and protease production. S. aureus AM23 and P. aeruginosa AM41 were selected as the highest biofilm and degrading enzymes producers. Furthermore, twenty-four methanolic and aqueous crude extracts derived from different medicinal plants in Egypt were screened for their antibacterial activity against both selected MDR strains. Methanolic extract of Eucalyptus camaldulensis leaf showed the greatest effect on the tested bacteria. Also, there was a synergistic effect of combined E. camaldulensis leaf extract and antibiotics (Gentamycin and Ceftriaxone) against tested organisms. Transmission electron microscopy showed changes in cell shapes, size, contents and cell envelop of antimicrobials treated bacterial cells compared to the control. Our findings proved that the leaf extracts of E. camaldulensis had great potential as antimicrobial agents in the treatment of infectious organisms.
