Fifty-one essential oils extracted from plants of known origin were tested for their antimicrobial activity against three bacteria, Pseudomonas aeruginosa, Staphylococcus aureus, Escherichia coli and four yeasts, Torulopsis utilis, Schizosaccharomyces pombe, Candida albicans and Saccharomyces cerevisiae using the drop diffusion method. All showed antimicrobial activity against at least one of t...

Total flavonoids contents and antibacterial activity of the extracts from the aerial parts of two Labiateae species, Nepeta menthoides Boiss. & Buhse and Thymus trautvetteri Klokov & Desj.-Shost. were determined. Quantitative determination of flavonoid contents was calculated in terms of quercetin equivalent in various extracts (50% methanol, chloroform and distilled water) by AlCl3 colorimetri...

Medicinal plants are the wealthy source of antibacterial agents and curatives. There is an urgent need for new antimicrobial agents, so the antimicrobial activity for Ruta graveolens L. and Ficus carica Linn. Crude extracts were evaluated for its inhibitory activity against some disease causing selected microorganisms. Root extract of Ruta graveolens L gave 8 and 7 mm inhibition zone against Es...

BACKGROUND Nearly all cultures from ancient times to the present day have used plants as a source of medicines. As a result, different remedies tended to develop in different parts of the world. Current strategies to overcome the global problem of antimicrobial resistance include research in finding new and innovative antimicrobials from plants. OBJECTIVES To determine the antibacterial activ...

rosa damascena, tripleurospermum disciforme and securigera securidaca were used as disinfectant agents and for treatment of some disease in folk medicine of iran. the antimicrobial effects of different fractions of seeds extract of s. securidaca, petals extract of r. damascena and aerial parts extract of t. disciforme were examined against some gram positive, gram negative and fungi by cup plat...

In an attempt to find out a new class of antimicrobial agents new series of Benzylidine-2imino-1,3-benzothiazole and other related products containing benzothiazole moiety were prepared. The synthesis was carried out by condensation of different aromatic aldehydes with benzothiazole derivative using different procedures. The synthesised compounds were characterized and evaluated for antimicrobi...

A new class of biologically active nanocomposites and modified polymers based on poly (vinyl alcohol) (PVA) with some organic compounds [II, IV, V VI] were synthesized using silver nanoparticles (Ag-NPs). All nucleophilic substitution interactions characterized by FTIR, DSC TGA. The biological activity the was evaluated against: gram (+) (staphylococcus aureus) (-): (Es cherichia coli bacteria)...

male and female leaves and fruits of eleven different taxons of iranian conifers (cupressus sempervirens var. horizontalis, c. sempervirens var. sempervirens, c. sempervirens cv. cereifeormis, juniperus communis subsp. hemisphaerica, j. excelsa subsp. excelsa, j. excelsa subsp. polycarpos, j. foetidissima, j. oblonga, j. sabina, platycladus orientalis and taxus baccata) were collected from diff...

PURPOSE The antiseptic qualities of aromatic and medicinal plants and their extracts have been recognized since antiquity, while attempts to characterize these properties in the laboratory date back the beginning of the XX(th) century. In the current study essential oils obtained from Pelargonium roseum (Geraniacea) were analyzed for their antibacterial and antifungal activities. METHODS The ...
