Materials and methods: Antibacterial activity of different extracts (n-hexane, dichloromethane, and methanol) o...
ABSTRACT: Chemical composition of Lavandula angustifolia was studied by solvent free microwave extraction (SFME) and hydrodistillation (HD) methods. 1, 8-cineole (42.7% and 37.9%), Camphor (26.1% and 21.3%) and Borneol (31.2% and 21.6%) were the major compounds that obtained by SFME and hydrodistillation, respectively. The antibacterial activity of extracted oils was investigated against Gram-p...
utopia has, for four centuries, accompanied that hope of progress and that striving for betterment. it now straggles against a widespread sense that this has been an illusion, or an impossible dream. the utopian idea can never entirely disappear, but utopia as a form of the social imagination has clearly weakened. if it cannot instill its vision in the public consciousness, the consequences...

Background: Recent trends in the production of functional foods and nutraceutical compounds indicate the important role of bioactive molecules in the treatment of human diseases. In this study, some phytochemical and nutraceutical properties of Ziziphus nummularia fruit extract harvested from the Poshtpar-Dashtestan forests were evaluated. Materials and Methods: The antioxidant activity and tot...
phytochemical investigations of piper sarmentosum roxb., yielded four compounds; three amides, identified as 3-(3’,4’,5’-trimethoxyphenylpropanoyl) pyrrolidine, 3-(4’-methoxyphenylpropanoyl) pyrrole, n -(3-phenylpropanoyl) pyrrole and a sterol namely β -sitosterol . 3-(4’-methoxyphenylpropanoyl) pyrrole was found for the first time in this piper species. all chemical constituents were tested fo...
Gum of Butea monosperma is used to treat microbial and fungal infections in folk medicine. To validate this use, the in- vitro antimicrobial activity of petroleum ether and alcoholic extract of Butea monosperma gum was evaluated against various microbial strains such as Staphylococcus aureus, Bacillus subtilis, Bacillus cereus, Salmonella typhimurium , Pseudomonas aeuriogenosa, Esch...
71 samples of milk and dairy products were collected from 18 cities throughout Iran. 93 strains of lactic acid bacteria (LAB) were isolated and assayed against four opportunistic patho gens including E. coli, proteus and klebsiella as gram-negative and S. aureus as a gram-positive organism. All indicators (organisms) were hospital strains. Among isolated bacteria, lactobacilli (37 isolates)...
the current study evaluated the general toxicity, antioxidant, antimicrobial, and cytotoxic activity of extracts obtained from the rhizomes of eremostachys azerbaijanica (labiatae) as well as analyzed the potent extracts using gc-ms. extracts of e. azerbaijanica in n-hexane, dichloromethane (dcm) and methanol (meoh) were prepared using a soxhlet apparatus. the antioxidant activity of the extrac...
Wide range of quinazolinone biological properties including: antibacterial, anticancer, and anti-inflammatory activities encouraged us to synthesis some fused quinazolinone derivatives. Anthranilic acid was condensed with chloro acylchloride followed by dehydration to form the benzoxazinone intermediate; subsequent addition of an amine provided the fused quinazolinones. Deoxyvasicinone which wa...
