backgrounds and objective: kombucha is a several thousand years old traditional fermented beverage originated from east. while black tea infusion is the common substrate for preparing kombucha, other herbal infusions can be applied for this reason too. common medicinal herbs or even waste herbal materials, like banana peel, could be suitable substrates for preparing kombucha analogues. in this ...

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...

objectives: the objective of this study was to analyze the fatty acid content, antioxidant, and antibacterial activities of hydro-methanolic extract of adonis wolgensis l. (a. wolgensis l.) growing wild in north of iran. materials and methods: oils of a. wolgensis l. was obtained by means of soxhlet apparatus from leaves and stems. methyl esters were derived from the oily mixtures by trans-este...

substituted 1, 2, 4- triazoles have shown multiple biological activities such as anti-inflammatory, anti fungal, etc. 5-mercapto triazoles were prepared from the potassium dithiocarbazinates. these triazoles were used for preparation of different derivatives by two different schemes. in the first scheme the mannich bases were prepared from 5- marcapto-s triazole quinazolines. the 5-marcato-s-tr...

fractions obtained from partitioning of aerial methanolic extract of euphorbia aellenii with chloroform (e2), ethyl acetate (e3), n-butanol (e4) and water (e5) were investigated in vitro for their phytotoxicity, insecticidal, anti-leishmanial, cytotoxicity, antibacterial and antifungal activities. sample e2 appeared to have significant phytotoxic activity. in the insecticidal screening study on...

antibacterial activity of the aerial extracts from xanthium brasilicum prepared in methanol, diethyl ether, petroleum benzene and an equal mixture of the three solvents were studied against bacterial laboratory standards and clinical isolates using the disk diffusion method. the best antibacterial results were obtained when methanol or the solvent mixture was used. the crude extract with the hi...

In this study, extracts and essential oils of Black and Red pepper and Thyme were tested for antibacterial activity against Escherichia coli O157: H7 and Staphylococcus aureus. Black and Red pepper and Thyme were provided from Iranian agricultural researches center. 2 g of each plant powder was added to 10 cc ethanol 96°. After 24 h, the crude extract was separated as an alcoholic extract and c...

Currently, the search for natural antimicrobial agents has increased. Thereat, plant extracts, products of fermentative processes, and microbial growth have been tested. Kombucha is a fermented beverage that resulted from fermentation infusion Camellia sinensis. There are reports about biological activities, such as anti-inflammatory, digestibility, antioxidant, antimicrobial, others. The study...

INTRODUCTION The aim of the study was to explore the in vitro antibacterial activity of seven ethanolic extracts of spices against high level gentamicin resistant (HLGR) enterococci isolated from human clinical samples. MATERIAL AND METHODS Two hundred and fifteen enterococcal strains were isolated from clinical samples. High level gentamicin resistance in ethanolic extracts of cumin (Cuminum...

Aim: To explore the in vitro antibacterial activity of seven ethanolic extracts of spices against the clinical isolates of enterococci. Methods: 215 enterococcal strains were isolated from clinical samples. Ethanolic extracts of Cumin (Cuminum cyminum), Cinnamon (Cinnamomum zeylanicum), Ginger (Zingiber officinale), Fenugreek (Trigonella foenum graecum) , Cloves (Syzygium aromaticum), Cardamom ...
