introduction: zhumeria majdae is an herbal plant which is only found in hormozgan province. the aim of this study was to compare the antimicrobial property and toxicity of essential oil (eo) and encapsulated form of the essential oil (efeo) of zhumeria majdae. materials and methods: first, the plant was dried, grinded, and its eo extracted by hydrodistallation. then, the eo was encapsulated by ...

as part of our ongoing interest in exploring the synthesis of antibacterial agent, we report an efficient, mild, one pot and chemoselective procedure for preparation of 3-poly (vinylbenzyl)-5,5-dimethylimidazolidine-2,4-dione as a antimicrobial agent from poly(vinylbenzyl chloride) and 5,5-dimethylhydantoin in the presence of a base in dmf as a solven. the ft-ir technique and melting point conf...

background scrophularia striata (scrophulariaceae family) is an herbaceous plant that is traditionally used for treatment of microbial infections. objectives antimicrobial and antioxidant activity of different extracts (methanolic, ethanolic, aqueous and ethyl acetate) from s. striata aerial parts was evaluated. materials and methods the antimicrobial activity of different extracts from s. stri...

quantitative structure-activity relationship (qsar) studies of a series of substituted 3-hydroxy-pyridine-4-ones and 3-hydroxy-pyran-4-ones as antibacterial and antifungal agents against a variety of microorganisms were performed. multiple linear regression approach was used as variable selection method. the antimicrobial activities of these compounds against staphylococcus aureus, aspergilus n...

synthesis, characterization, spectral and theoretical calculations of sodium tetrafluoroborate (iii) (stfb) has been studied in this research. sodium tetrafluoroborate (iii) was synthesized by a sonochemical method and characterized by ir, uv/vis, 11b-nmr and mass spectrometer techniques. the nano compound was characterized by scanning electron microscopy (sem), x-ray powder diffraction (xrd) a...

hyssopus of­ficinalis l. is one of the most important medicinal plants. medicinal herbs are contaminated by microorganisms. conventional methods for reducing of microbial loads such as ethylene oxide, propylene oxide and also use of steam are hazardous and instead, non-thermal process such as microwave and gamma radiation are being used widely in order to eliminate the microbial contaminations ...

background and objectives: dental caries is still remained as a major health problem. this problem has created a new interest to search for new antimicrobial agents from various sources including medicinal plants. since limited data is available so far regarding the antibacterial effect of coriandrum sativum seed and dentol drop against streptococcus mutans, this study aims to assess this activ...

background: infectious diarrhoea is an emergent problem in both developing and developed countries for high rates of mortality in infants. in recent years, drug resistance to microbial pathogens has been commonly reported from all over the world. medicinal plants represent a rich source of antimicrobial agents. plants are used medicinally in different countries especially in india and are a sou...
