molds are one of the most important causes of food spoilage that produce toxic substances called mycotoxins, which endanger the consumer health. the adverse effects of synthetic food preservatives consumption made researches to focus on application of natural preservatives in order to increase shelf life of food as well as prevention of harmful effects of chemical preservatives. the present stu...

seaweeds have caused an emerging interest in the biomedical area, mainly due to their contents of bioactive substances which show great potential as anti-inflammatory, anti-microbial, anti-viral and anti-tumoral drugs. despite the diversity in quality and quantity of the mediterranean tunisian coast flora, with its large contains of marine organisms and seaweeds, most of them have not yet been ...

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...

AIM This study was to evaluate in vitro anti-fungal activity of aqueous and hydroethanolic from medicinal plants extracts collected in Côte d'Ivoire. MATERIALS AND METHODS Plants extracts were prepared by homogenization and separately incorporated to Sabouraud agar using the agar slanted double dilution method. Ketoconazole was used as standards for anti-fungal assay. The anti-fungal tests we...

The Chenopodium album extracts served as a capping agent in the present work to synthesize Bi2O3 Nps. synthesized nanoparticles were confirmed by various spectroscopic techniques. Nano-structured was measured have mean size of 79.99nm. Anti-fungal activity Nps also evaluated. been shown impressive antifungal efficacy against variety fungal species. It's powerful anti-fungal medication that outp...

an efficient synthesis of some novel coumarin derivatives via 1, 4- michael addition of indole to coumarin chalcones catalyzed by cellulose sulphonic acid (csa) under solvent free conditions is described. the corresponding michael addition products were obtained in good to excellent yield. the synthesized compounds were screened for their antibacterial activity against e. coli, s. aureus and an...
