4′,5,7-Trihydroxy-3′-prenylflavanone was synthesized and tested for antibacterial effects against Bacillus subtilis, Escherichia coli, Staphylococcus aureus and Pseudomonas aeruginosa. The synthesized compounds were characterized using UV, IR, MS and 1H and 13C NMR data. The antibacterial screening of the synthesized compounds were performed in vitro by the filter paper disc diffusion method.

Carbapenem resistance due to acquired metallo-beta-lactamases (MBLs) is considered to be more serious than other resistance mechanisms. The aim of this study was to evaluate the antibacterial activity of Zataria multiflora Boiss and Carum copticum plants on IMP-producing P.aeruginosa strains. This experimental study was carried out on hospitalized burn patients during 2011 and 2012. Antibiotics...

Currently, diseases caused by infection with pathogenic microorganisms are increasing, this is indicated the increasing interest in antibacterial substances. This research was conducted on stem of pelawan plant (Tristaniopsis merguensis Griff.) aim identifying secondary metabolites contained extract n-hexane, ethyl acetate, and methanol which have potential to activity. Determination profile co...

Neem (Azadirachta indica A. Juss) oil (NO) was assayed against forty-eight isolates of Escherichia coli by standardised disc diffusion test and microdilution test. By molecular biology characterization, fourteen isolates resulted in diarrheagenic E. coli with sixteen primer pairs that specifically amplify unique sequences of virulence genes and of 16S rRNA. The NO showed biological activity aga...

Measles is a killer disease of children in Uganda. The treatment of the disease is mainly directed at the secondary microbial infections. A large proportion of the population in Uganda still relies on the use of herbal remedies, which have been claimed to produce beneficial responses. In this study, the efficacy of Warburgia ugandensis and Zanthoxylum chalybeum against common bacteria and fungi...

Studies on the antibacterial activities of the leaf extract of Citrullus colocynthis (Cucurbitaceae), a medicinal plant used for the treatment of various ailments was carried out using agar disc diffusion technique. The results revealed that the crude acetone extract exhibited antibacterial activities against Pseudomonas aeruginosa with zones of inhibition measuring 14.0mm. The chloroform leaf ...

Invitro antibacterial and antifungal activities of methanolic extract of osbeckia wynaadensis was evaluated in the present study for the first time by disc diffusion method using five bacterial strains (S. pneumonia, B.cereus, A. hydrophila , V. cholera and MRSA) and five fungal strains (Candida albicans, Aspergillus niger, Streptomysis Greusis, M. purpureus and Aspergillus fumigate) respective...

Background & Aim: The major aim of this study was to determine the antibacterial activity of the essential oils from five medicinal plants. Experimental: The hydro-distillation essential oils from five plant species, including Satureja bachtiarica, Zataria multiflora, Thymus daenensis, Thymus carmanicus, and Ziziphora tenuior (Lamiaceae) which are e...

musa sapientum (m.sapientum) commonly known as ‘banana’ is widely used in bangladeshi folk medicine for the treatment of various ailments including diarrhea. hence, the present study was designed to investigate antidiarrheal, antioxidant and antibacterial potential of the methanolic extract of m.sapientum seed (mmss). the extract was studied for antidiarrheal property using castor oil and magne...
