UNLABELLED Ear infection is one of the common diseases occurring throughout the world. Different etiological agents are responsible for ear infections. AIM To assess the antimicrobial potential of Terminalia arjuna leaves and bark extracts against Staphylococcus aureus, Acinetobacter sp., Proteus mirabilis, Escherchia coli, Pseudomonas aeruginosa and Candida albicans, pathogens causing ear in...

Extacts of root of Glycyrrhiza glabra linn were prepared by using n-hexan, toluene, tetrahydrofuran, ethylacetate, and ethanol and their antioxidant and antimicrobial activities were measured. Secondary metalbilites like flavonoids, alkaloids, terpenoids, glycosides, and steroids were measured and it was found that highly polar solvents ike ethyl alcohol, ethyl acetate and THF extract more meta...

The genus Penicillium is well known for its importance in drug and food production. Certain species are produced on an industrial scale for the production of antibiotics (e.g. penicillin) or for insertion in food (e.g. cheese). In the present work, three Penicillium species, part of the natural mycobiota growing on various food products were selected - P. ochrochloron, P. funiculosum and P. ver...

 In human cell lines, woodsmoke caused more DNA damage than traffic-generated PM per unit mass and was found to induce lung cancer in mice. Oncogene mutations in human patients with advanced non-small cell lung cancer were associated with exposure to wood smoke as well as tobacco smoking. Organic extracts of ambient particulate matter containing substantial quantities of woodsmoke were found t...

The aim of our research is the screening of extracts of marine sponges for their antifungal activity against phytopathogenic fungi. The in vitro screening of hydroalcoholic and organic extracts of ten marine sponges from Atlantic coast of Morocco against five phytopathogenic fungi (Fusarium oxysporum f.sp. melonis, Fusarium oxysporum f.sp. radicis-lycopersici, Fusarium oxysporum f.sp. ciceris, ...

Aim: To compare the antimicrobial efficacy of five Medicinal plant extracts against two strains of Streptococcus mutans causing dental caries using Agar well diffusion method. Materials and methods: Five plant extracts were prepared by soxhlet extraction method using organic solvent. These extracts were tested against Streptococcus mutans MTCC 497& MTCC 890 causing dental caries by Agar well di...

Piptoporus betulinus is a wood-rotting basidiomycete used in medicine and biotechnology. However, to date, no indoor method for cultivation of this mushroom fruiting bodies has been developed. Here we present the first report of successful production of P. betulinus mature fruiting bodies in artificial conditions. Four P. betulinus strains were isolated from natural habitats and their mycelia w...

A test system based on the use of ion exchanges, gel filtration on Sephadex and extraction with organic solvents is described. This system provides information on the stability, molecular size, charge, and polarity of the pharmacologically active compounds in the aqueous plant extracts. Knowledge of these properties permitted the development of an isolation method for a glucose present in the a...

The air dried powdered plant materials were extracted with different organic solvents, screened for phytochemicals and analyzed for their biological activities. The antioxidant potential was evaluated by scavenging of DPPH radical, TPC and TFC, while antimicrobial activity by disc diffusion assay against a set of bacterial and fungal strains. Ethylacetate extracts showed higher free radical sca...

Organic extracts (ethanol, petroleum ether and chloroform) of two medicinal plants Lawsonia inermis L. and Mimosa pudica L. were proven for antibacterial properties against 15 Gram-positive and Gram-negative human pathogenic bacteria. Among the three types of extracts tested, ethanol extract was found to possess maximum antibacterial activity. The diameter of the zone of inhibition of bacterial...
