Optimisation of Three Essential Oils against Salmonella spp. and Escherichia coli by Mixture Designa.

The aim of this work is to optimise the antibacterial activity of essential oils (EOs) from Eucalyptus camaldulensis (ECEO), Mentha pulegium (MPEO) and Rosmarinus officinalis (ROEO) plants against Salmonella spp. and Escherichia coli. The qualitative antimicrobial effect was assessed using the disc diffusion method, the broth microdilution method was used to determine the minimum inhibitory concentrations (MIC).

The Synergistic Effect of Three Essential Oils against Bacteria Responsible for the Development of Lithiasis Infection: An Optimization by the Mixture Design.

The present study aimed to determine the chemical composition and the synergistic effect of three plants' essential oils (EOs), (ECEO), (MPEO), and (ROEO), against three bacterial strains, , , and , in order to increase the antimicrobial effectiveness by the use of a low dose of essential oils, consequently decreasing the toxicity and negative impact. For this reason, an augmented simplex-centroid mixture design was used to build polynomial models in order to highlight the synergy between the essential oils against bacterial strains. Antimicrobial effect screening was performed by the disc diffusion method and the minimal inhibitory concentrations (MIC) were also studied.

Chemical Compounds Identification and Antioxidant and Calcium Oxalate Anticrystallization Activities of L.

The plant L. has several biological activities and a great curative and preventive power against chronic diseases. For this purpose, the objective of this work is to valorize the fruit peel of this plant in the field of phytomedicine, by quantifying and identifying its bioactive compounds and by evaluating their antioxidant and anticrystallization activities against calcium oxalate.

Chemical compounds as well as antioxidant and litholytic activities of Arbutus unedo L. leaves against calcium oxalate stones.

Objective: The present study aimed to quantify and identify the bioactive compounds of the Arbutus unedo L. leaves in order to evaluate both their antioxidant properties and litholytic activities against calcium oxalate stones.

Methods: This survey was carried out using hydroalcoholic extract (E.

Phytochemical screening and inhibitory activity of oxalocalcic crystallization of L. leaves.

The present study is focused on the experimental verification of the efficiency of L. leaves against the crystallization of calcium oxalate. The inhibition of crystallization has been studied in vitro with the absence and the presence of the different concentrations of the infusion and hydroalcoholic extract of the plant.
