in this study, we have examined the antioxidant activity and total phenolic content of different extracts (including water, methanol, water : methanol and acetone) of nerium oleander l. grown in the north of iran by employing various in-vitro assay, i.e. dpph free radical scavenging, reducing power and total antioxidant capacity through the mo (vi) reduction. the extracts showed different level...

background: the application of natural compounds including green tea extract (gte) in food and pharmaceutical industries is limited. encapsulation in nanoliposomes could be used as a delivery system to protect these compounds during processing and storage. objective: in this study encapsulation of green tea extract in nanoliposomes and evaluation of its antibacterial, antioxidant and prebiotic ...

starting from readily available 2-substituted-4-methylthiazole-5-carboxylic acid hydrazide (1), the title compounds were prepared. the reaction of compound 1 (r=ch3) with formic acid yielded 1-(formyl)-2-(2,4-dimethylthiazole-5-carboxyl) hydrazine (2). refluxing the latter with phosphorous pentasulfide in xylene afforded compound 3, the reaction of compound 2 with phosphorous pentoxide afforded...

three native turkish medicinal and aromatic plants (artemisia absinthum, artemisia santonicum and saponaria officinalis) were investigated to analyze their antioxidant activity, total phenolic content and antimicrobial activity. their total antioxidant activity was determined by using a β-carotene bleaching assay and their antimicrobial activity was determined by utilizing an agar disc diffusio...

background: we aimed at evaluating the toxicity effects of low (subtoxic) concentrations of silver nanoparticles (agnp, 5-10 nm) in human hepatoblastoma (hepg2) cell line after and during a period of about one month. methods: xtt and mtt assays were used to draw a dose-response curve ic50 (half maximal inhibitory concentration) value of the agnp on hepg2 cells was calculated to be 2.75-3.0 mg/l...
