In this study, methanol and ether extracts of five endemic Asperula species (Rubiaceae) from Turkey (A. antalyensis, A. brevifolia, A. pseudochlorantha, A. purpurea subsp. apiculata and A. serotina), used in the traditional system of medicine, were tested for antimicrobial activity by the agar well diffusion method and the broth dilution method. The most active species were Asperula brevifolia ...

Objective: Punica granatum, commonly known as pomegranate, has emerged as a medicinal plant with potential antimicrobial activity. The present study was planned to evaluate this activity against both Gram positive Staphylococcus aureus (S. aureus) and negative Pseudomonas aeruginosa (P. aeruginosa) bacteria as well as against pathogenic yeast, Candida albicans (C. albicans). Material and Metho...

The present work was designed to evaluate the in vitro lipid peroxidation inhibitory and antimicrobial activities of the methanol extract of Phyllanthus niruri (MEPN) (Family:   Euphorbiaceae) .   Lipid peroxidation was measured by the optical density of the prepared solutions (10-320 µg/ml) and then the percent inhibition was calculated. Ascorbate/FeSO 4 -induced p...

background and objective: considering the increasing tendency of public towards green consumption and the dangers of artificial additives, this study aimed to assess antibacterial activity of essential oils of cinnamomum zeylanicum, mentha piperita l., zataria multiflora boiss and thymus vulgaris against three important pathogenic and spoilage bacteria (pseudomonas fluorescens, erwinia carotovo...

conclusions the excellent antimicrobial activities of the tested eos might be due to their major phenolic or alcoholic monoterpenes with known antimicrobial activities. hence, these eos can be possibly used as an antimicrobial agent in treatment and control of oral pathogens. results the tested eos inhibited the growth of examined oral pathogens at concentrations of 0.015-16 µl/ml. among the ex...

conclusions the results of the present study indicate that brazilian propolis demonstrated in vitro anti-microbial efficacy against s. mutans and c. albicans. results the antimicrobial efficacy of hexidine against s. mutans and e. coli was higher compared to that of c. albicans. the brazilian propolis (p) mr showed antimicrobial action against s. mutans and c. albicans. the antimicrobial effica...

4-(acetoacetamido) arsanilic acid (II), which was then condensed with aryl aldehydes. The resulting product on reaction with hydrazine hydrate and hydroxyl amine hydrochloride yielded Pyrazolines (IV) and Isoxazolines (V), respectively. The antimicrobial activity of compounds against a number of microorganisms was evaluated. Some of these compounds showed significant antimicrobial activity

Background: Plant-derived Essential Oils (EOs) have shown remarkable antimicrobial activity against spoilage and pathogenic microorganisms isolated from food products. The objective of the current study was to determine in vitro antimicrobial effects of selected EOs against these microorganisms. Methods: Antimicrobial activity of EOs against food-borne and spoilage microorganisms was screened ...

Seven reported xanthate ligands and their new Fe(II) complexes of formulaNa[Fe(R-OCSS)3], where R is ethyl-, propyl-, butyl-, pentyl-, Hexyl-, heptyl- and octyl-xanthate have been synthesized. They have been characterized using elemental analysis, molar conductance, FT-IR, UV-Vis and 1H NMR spectroscopic techniques and melting-, decomposition-points for ligand...
