the methanolic extracts, infusions, decoctions and hydrosols of six plants were investigated for their total phenolic contents, antioxidant and antimicrobial activities: mentha piperita (peppermint), thymus vulgaris   (thyme), melissa officinalis (lemon balm), ocimum basilicum (basil), rosmarinus officinalis (rosemary) and     salvia officinalis     (sage) (lamiaceae). total phenolic contents w...

diabetes mellitus is a metabolic disorder affecting carbohydrate, fat and protein metabolism that affects nearly 10% of the population every year. the treatment of diabetes mellitus has been confined to use of oral hypoglycemic agents and insulin, the former being reported to possess serious side effects. this leads to increasing demand for herbal products with antidiabetic factor with little s...

the aim of the study is to examine in-vitro antioxidant and antimicrobial activity of the acetonic and methanolic extracts of the mushrooms boletus aestivalis, boletus edulis and leccinum carpini. antioxidant activity was evaluated by using free radical scavenging activity and reducing power. in addition, total content of phenol and flavonoid in extracts were determined as pyrocatechol equivale...

introduction: oxidative stress seems to play a critical role in the degeneration of dopaminergic neurons in parkinson’s disease (pd). antioxidant compounds can deactivate and scavenge free radical. olive leaves are considered as a useful source of phenolic compounds. therefore, this study was designed to investigate the effects of methanolic olive leaf extract (ole) on neurobehavioral activity ...

background & aim: glycyrrhiza l. (fabaceae) consists of perennial herbs grow in sandy soils with hard lightness. three species of the genus grow in iran, among them g. glabra l. has the widest distribution. it is well known in english as licorice and the root extract includes flavonoids and glycyrrhizin are used widely in medicine, food industry, tobacco products and other industries. liqui...

this study was conducted in acompletely randomized block design with three replications using three concentrations of 107, 105, and 103cfu/ml of azotobacter isolated from the rhizosphere of karun varieties of barley (az. salentris) and standard az.chrococom along with control (zero concentration of bacteria). the aim of this study was to study the reactions of barley plantin response to inocula...

background: elicitors can trigger defense responses and activate specific genes involved in secondary metabolite biosynthesis. objective: for understanding sa-treatment signaling pathway we determined defense-related compounds and enzymes in s. marianum hairy root cultures. methods: 28 day old hairy roots were treated by salicylic acid (6 mg/50 ml culture) for different times (24, 48, 72, 96 an...

Medicinal plant possessed antifungal effects by many mechanisms, they caused membrane disturbance resulting in the loss of integrity, inhibited DNA transcription and reduced cell populations, activity fungal antioxidant enzymes biofilm formation. The current review discussed medicinal plants.

drought stress is one of the most important factors limiting the survival and growth of plants in the different habitats of iran. detailed knowledge about the ecophysiological responses of native plants to drought stress could contribute to the success of breeding and re-vegetation programs. six wild populations of anthemis tinctoria, were assigned to four drought treatments, i.e. well-watered ...
