honey has antibacterial activity. the aim of this study was to evaluate the antibacterial activity of honey on streptococcus mutans and lactobacillus.in this in vitro study, solutions containing 0%, 5%, 10%, 20%, 50% and 100%(w/v) of natural hamadan honey were prepared. each blood (nutrient) agar plate was then filled with dilutions of the honey. the strains of bacteria were inoculated in blood...

string from substituted selenobenzamides (2) a series of 2- arylselenazoles (3-7) were prepared. the antibacterial activity of compounds 3-7 against a number of microorganisms were determined. some of these compounds showed significant antibacterial activity

Herbal extract stabilized green synthesis of nanoparticles is an alternative reducing agent for chemical synthesis. In this manuscript, gold (AuNPs) has been performed using aqueous black tea. The effect tea concentration on the morphology particles was studied. Formation, functional groups, crystalline phase, and changes were characterized by UV-Vis spectrophotometer, Fourier transforms spectr...

introduction: the aims of this study were i) to define the chemical constituents of cuminum cyminum (cumin) essential oil, ii) to compare the antimicrobial activity of this oil to that of chlorhexidine (chx) and co-trimoxazole on planktonic and biofilm forms of bacteria isolated from the teeth with persistent endodontic infection and iii ) to compare the cytotoxicity of these medicaments on l92...

background: woodfordia fruticosa is used traditionally as antidysenteric compound for fodder animals. stem and flower extracts are previously flourished for their antibacterial activity. leaves are also equally important, which are preliminary screened for their bioactive components in present study. objective: evaluation of antibacterial activity of leaves of w. fruticosa and detection of thei...

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...

objective(s): silver nanoparticles (ag nps) are not only specific physical and chemical properties but also are considered for their antibacterial activity and ecofriendly.materials and methods:in this study a simple, cost effective biologically method for ag+reducing to ag nps using echinops extractas a stabilizer, and reducing agent.ag nps were analyzed using uv-vis spectrometry,tem, xrd and ...

the antibacterial activity of a series of ionic liquids containing short-chained 1-alkyl-3-methylimidazolium cations ([cnmim+]; n = 2, 4, 6 and 8) and bis (trifluoromethylsulfonyl) imide anion ([tf2n]) against e. coli and b. subtilis was measured, for the first time. all ils used in this work were synthesized and analyzed by fourier transform infrared (ft-ir) spectroscopy, nmr, and karl-fischer...
