A novel azo-Schiff base ligand (L) was prepared by reacting 2-hydroxy-5-(pyridine-4-yldiazenyl) benzaldehyde with 1,2-phenylenediamine. Moreover, Silver nanoparticles (Ag-NPs) and Cadmium sulfide nanoparticles (CdS-NPs) were prepared by employing azo-Schiff base ligand (L) as capping and reducing agent. The solid-state fluorescence spectroscopy was used to investigate the interaction between L ...

The root and flowers of Butea monosperma (Lam.) were extracted with methanol. Extensive chromatographic separation and purification with the organic solvents was done. Four phytochemicals were separated and their structures were established based on various spectroscopic techniques. Isolated crude extract was subjected for antibacterial activity against gram-negative and gram-positive bacteri...

A new series of 2-(5-nitro-2-heteroaryl)-1,3,4-thiadiazole derivatives, including nitro furan, nitro thiophene and nitro imidazole, were synthesized and screened in vitro for their inhibitory activity against eight bacterial strains. The results showed that most of the synthesized compounds were active against Gram-positive bacteria, determined by MIC method. Among them, compounds <str...

in this study, methanol and ether extracts of five endemic asperula species (rubiaceae) from turkey (a. antalyensis, a. brevifolia, a. pseudochlorantha, a. purpurea subsp. apiculata and a. serotina), used in the traditional system of medicine, were tested for antimicrobial activity by the agar well diffusion method and the broth dilution method. the most active species were asperula brevifolia ...

Sudarshan Churna (SC) is very potent Ayurvedic medicine ; composed of 42 medicinal plants, which is used traditionally in treatment of malaria, viral fever, and bacterial infection. The Present study was designated to evaluate the antimicrobial activity of aqueous extract of Sudarshan Churna (ASC) using the paper disc diffusion method. The ASC was found active against the gram-negative b...

nickel(ii) complex of [nil2](clo4)2, where l is an unsymmetrical tridentate ligand of 2-(2-aminoethyl)imino-3-butanone oximehas been synthesized by a template condensation reaction. the complex was characterized on the basis of microanalytical, spectroscopic, and other physicochemical properties. x-ray diffraction study of the complex reveals nickel(ii) center in a distorted octahedral environm...

background: due to multiple drug resistance against antimicrobial drugs for treatment of infectious disease, investigations to discovering new antibacterial compounds from natural sources have been designated. objective: according to antimicrobial effects of some capparis species, this study was carried out to evaluate the antimicrobial activity of the extract and fractions of capparis cartilag...
