methanolic and aqueous extracts of dendrophthoe falcata linn. leaves which belongs to the loranthaceae family, were evaluated through dpph (1, 1-diphenyl -2-picryl-hydrazyl), antilipid peroxidation and nitric oxide scavenging methods to assess the antioxidant activity. methanolic and aqueous extracts of dendrophthoe falcata leaves were also evaluated for their anti-inflammatory activity by carr...

paris polyphylla smith var. yunnanensis, has been used in traditional chinese medicine for its antibiotic and anti-inflammatory properties; in addition it has been used to cure liver cancer in particular. in this current study, β-ecdysterone (1) and three pennogenin steroidal saponins (2-4) were isolated from the etoh extract of paris polyphylla var. yunnanensis, and then tested for their antit...

leptadenia reticulata was reported to be used for several medicinal purposes. the present study was undertaken to evaluate anti-inflammatory, analgesic and lipid peroxidation inhibition activities of l. reticulata. the anti-inflammatory assay was performed by λ-carrageenan and formalin induced paw edema test. pro inflammatory mediators (il2, il6, tnf-α) in serum of treated and control organism ...

ba ckground: although it is widely accepted that the pre-school age is a critical period  in  the  development of  obesity,  there  are  few  published data  on  factors contributing to variation of total energy expenditure in this age group.to investigate the contribution of body composition, gender and activity on total energy expenditure (tee) in pre-school children. m ethods: the total ener...

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...
