objective(s) due to increasing emergence of drug-resistance in helicobacter pylori isolates, traditional plants are potentially valuable sources of novel anti-h. pylori agents. in this research, anti-h. pylori activity of the organic extracts of twenty native iranian plants was determined against ten clinical isolates of h. pylori. materials and methods disc diffusion was used to determine the ...

it has been investigated the in vitro antioxidant properties of ethanol extracts of the contained-allantoin plants in this study. contained-allantoined plant samples plantago lanceolata, plantago major, robinia pseudoacacia, platanus orientalis and aesculus hippocastanum were tested at different concentrations. the antioxidant activities of plant samples were analysed by 1,1- diphenyl-2-picrylh...

methanolic extract of whole plant of amaranthus viridis l (meav), was screened for antinociceptive activity using acetic acid induced writhing test, hot plate test and tail immersion test in mice. in a similar way a screening exercise was carried out to determine the antipyretic potential of the extract using yeast induced pyrexia method in rats. administration of the extracts was applied to bo...

conclusions silver nanoparticles were observed to have additive effects with essential oil against staphylococcus epidermidis and s. aureus. the obtained results suggest the need for further investigations of the antibacterial effects of the combination of silver nanoparticles with other plant extracts and essential oils. results the results of the experiment showed that the mic and minimal bac...

conclusions the bacterial isolates exhibited strong biofilm formation potential, while the extracts of acacia arabica significantly inhibited biofilm formation among the isolates and, therefore, could be executed in the development of cost-effective biofilm inhibitor medicines. results pseudomonas aeruginosa (kc417303-05), staphylococcus hemolyticus (kc417306), and staphylococcus hominis (kc417...

This study evaluated the effects of two Korean traditional plant extracts (Diospyros kaki THUNB. leaf; DK, and Nelumbo nucifera leaf; NN) on the fermentation, functional and sensory properties of herbal yogurts. Compared to control fermentation, all plant extracts increased acidification rate and reduced the time to complete fermentation (pH 4.5). Supplementation of plant extracts and storage t...

Objective(s): To evaluate the influences of aqueous extracts of plant parts (stem, leaves, and root) of Portulaca oleracea L. on bioformation of silver nanoparticles (AgNPs).Materials and Methods: Synthesis of silver nanoparticles by different plant part extracts of Portulaca oleracea L. was carried out and formation of nanoparticles were confirmed and evaluated using UV-Visible spectroscopy an...

antimicrobial activity of plant extracts in traditional medicine on bacteria and fungi has been identified. medicinal plants have been used since ancient times as a food coloring and flavoring agents. also, plant extracts have been used for the prevention of diseases caused by food borne pathogens. with the use of active packaging that can interact with the environment and product, increased sh...
