Due to the emergence of bacterial resistance in phytopathogenic microorganisms, it is necessary search for new treatment alternatives these pathogens. Natural extracts are a potential source bioactive compounds that can act against such strains. The antibacterial activity Larrea tridentata bacteria with public health importance has been documented; however, few reports cover pathogens associate...

allelopathy is one of the valuable tools in weed management that recently is considered in sustainable agriculture and reduces herbicide rate challenges. in order to study the allelopathic effects of rye (secale cereal l.) on six weed spices seeds including milk thistle (silybum marianum l.) gaertn, wimmer ryegrass (lolium rigidum gaudin), lesser canarygrass (phalaris minor retz.), charlock mus...

background: inflammation is a dynamic process that is elicited in response to various harmful stimulantsthat may threaten the well-being of the host. herbs have been traditionally used as anti-inflammatory agents since very early times. rubia tinctorum l. is one of these herbs that havebeen used for treating inflammatory diseases in iranian traditional medicine. objective: this study aims at co...

the aim of the present research was focused on the antibacterial, preliminary phytochemical and pharmacognostical properties of vicoa indica (l.)dc. via in vitro approach. the aqueous and organic solvent (hexane, chloroform and methanol) extracts from the leaves of vicoa indica (asteraceae) were tested against escherichia coli, klebsiella pneumoniae, salmonella typhi, vibrio parahaemolyticus, v...

The anti-ischemic effect of aqueous and ethanolic extracts of Nigella sativa L. seed was studied using a four-vessel occlusion model in rats. The ischemia was evaluated by optical and transmission electron microscopy. After 20 min of forebrain ischemia, agents were administered intraperitoneally after reperfusion. Both extracts comprised an alkaloid. In ischemic rats, the aqueous (1 g/kg) and e...

Background: Escherichia coli (Gram-negative bacilli) inflicts large economic losses on the poultry industry and is one of most important causes diseases. The indiscriminate use antibiotics has contributed to today’s increasing prevalence drug-resistant strains, which their emergence appears exceed discovery new drugs. Therefore, several attempts have been dedicated find compounds as effective a...
