Background & Aims: Microorganisms are protected from antimicrobial agents when placed in biofilm structure. Biofilm-producing microorganisms are responsible for many problems in industry and medicine; therefore, it is essential to find new techniques for removing and inhibiting biofilms. This study aimed to examine the antimicrobial effect of Eucalyptus camaldulensis alcoholic extracts against ...

three extracts of pulicaria dysenterica were examined for antibacterial activity using the agar disk-diffusion method against six bacterial strains. some of these extracts were found to be active against some bacterial strains. the methanolic extract exhibited a superior level of antibacterial activity. all of the extracts were active against vibrio chlorea.

?-Amylase inhibitory activities of ethanol extracts from six selected Iranian Salvia species (S. hydrangea DC., S. hypoleuca Benth., S. officinalis L., S. reuterana Boiss., S. verticillata L. and S. virgata Jacq.) were examined, using in vitro model. In addition, antioxidant capacities (DPPH• radical scavenging) and total flavonoid cotents of the extracts were also determined. The results showe...

The study was aimed to evaluate antioxidant activity of methanolic and aqueous extracts of Bergenia ciliata (Haw.) Sternb. rhizome. Total phenolic content was determined in both extracts. Free radical (DPPH ● and ● OH) scavenging potential of the extracts revealed that both extracts to be active radical scavengers. Reducing (Fe-Fe) power and lipid peroxidation inhibition efficiency (TBARS assay...

background:   objective: the aim of this study was to investigate the effects of aqueous and hydro-alcoholic extracts of lettuce seed on testosterone level and spermatogenesis.   materials and methods: in this experimental study 24 adult male nmri mice weighing 20-25gr were purchased. animals were randomly divided into 4 groups: controls, hydro-alcoholic (200 mg/kg) and aqueous extracts (50, 10...

It has been reported that latex and extracts of different species of Ficus are cytotoxic to some human cancerous cell lines. In this study, cytotoxicity of fruit and leaf extracts as well as the latex of Ficus carica L. on HeLa cell line were evaluated. Ethanolic extracts of leaves and fruits were prepared through percolation and ethyl acetate and dichloromethane extracts were prepared by reflu...

The present study investigates the antioxidant, anticancer, anticholinesterase, anti-genotoxic activities and phenolic contents of flower, fruit and seed methanol extracts of Hypericum retusum AUCHER. The amounts of protocatechuic acid, catechin, caffeic acid and syringic acid in methanol extracts were determined by HPLC. Total phenolic content of H. retusum seed extract was found more than fru...
