the hypotensive effect of garlic has been well-documented in human subjects and animals. since endothelial activity regulates vascular reactivity in physiological and pathophysiological conditions, the aim of the present study was to investigate the effect of garlic on endothelium-dependent and independent relaxation of rat aorta for elucidation of mechanism of the garlic anti-hypertensive effe...

herbs have been used for its medicinal properties from several thousand years ago. herbs, essences and extracts, possess a variety level of biological activities and antimicrobial activities of a large number of them have been proved. eucalyptus is one of these plants which the anti-virus effects of its extract has long been used to treat influenza and colds in most parts of the world. the aim ...

background: diabetes mellitus is considered one of the 5 principal causes of death in the world and is recognized as a global public health issue because of its multifactorial facets affecting essential biochemical processes in the body. this study investigated the antidiabetic and antidyslipidemic activities of the aqueous extract of cochlospermum planchonii (c. planchonii) leaves in streptozo...

The objective of this study was to evaluate the feasibility of an aqueous process to extract the residual oil from sunflower press cakes using a co-rotating twin-screw extruder. Two different configurations were tested: the expression fromwhole seeds followed by the aqueous extraction, in two successive apparatus or in the same one. For the aqueous extraction stage, the oil yield depended on th...

abstract anti-nociceptive activity of aerial parts of phytolacca americana were investigated, using the hot plate method in mice. results of the present study showed that the aqueous methanolic extract of aerial parts of p. americana produced a statistically significant increase in pain threshold after 30 min, in comparison with the control, at adose of 190 mg kg-1 (p<0.001). the activity was c...

Oil oxidation is significant for acceptability, nutritional quality, and toxicity of edible oils. Antioxidant supplementation oil a common fundamental strategy improving its oxidative stability prolonging induction time. Ginger contains natural antioxidants such as phenolic flavonoid compounds. extracts were prepared by extraction with different solvents (methanol, ethanol, acetone water). Etha...

the oxidation of lipids change organoleptical properties, nutritional value and shelf life of oils, and produce undesirable compounds that are not safe for customer”s health. there is many methods for prevention of oxidation such synthetic antioxidants, (bha, bht, tbhq, gallatester).synthetic antioxidants, have undesirable effects such cancer, motation in human body, therefore it was removed fr...

introduction: previously, we demonstrated that i.p. injection of aqueous extract prepared from aerial parts of drosera spatulata (droseraceae) can induced remarkable analgesia in both phases of formalin test in rats. because, analgesia induced in acute phase of formalin test mainly mediated by activation of central analgesic mechanisms and also paragigantocellularis (pgi) nucleus is part of bra...

objective: in the present study, the effects of aqueous saffron extract (crocus sativus l.) on the acquisition and reinstatement of morphine-induced conditioned place preference (cpp) in mice were investigated. materials and methods: subcutaneous administration of morphine (40 mg/kg for four days) produced place preference. intraperitoneal administration of aqueous extract (40 and 80 mg/kg for ...
