EPR spectroscopy, in a constant-frequency field-swept experiment, was used to determine the resonant magnetic field, g-factor, line width, and hyperfine constant for diphenyl picrylhydrazyl at room temperature manganese (II) chloride cryogenic temperatures (using liquid nitrogen). Diphenyl determined be free radical, indicated by g-factor of 2.022, with field 3.23 kG microwave frequency 9.14 GH...

BACKGROUND The main objective of this study was the phytochemical characterization of four indigenous essential oils obtained from spices and their antibacterial activities against the multidrug resistant clinical and soil isolates prevalent in Pakistan, and ATCC reference strains. METHODS Chemical composition of essential oils from four Pakistani spices cumin (Cuminum cyminum), cinnamon (Cin...

A microbioautographic method for the identification of pteroylglutamic acid derivatives and their glutamyl conjugates is described. Chromatograms or pherograms of mixtures of the compounds are treated with chicken pancreas conjugase, followed by tetrazolium bioautography. This combined procedure allows qualitative and semi-quantitative analyses of folate compounds in biological material in the ...

The present study deals with the antimicrobial, antioxidant, and functional group analysis of Heliotropium bacciferum extracts. Disc diffusion susceptibility method was followed for antimicrobial assessment. Noteworthy antimicrobial activities were recorded by various plant extracts against antibiotic resistant microorganisms. Plant flower extracts antioxidant activity was investigated against ...

The increasing occumnce of opportunistic systemic mycoses associated with the use of immunosuppressive drugs and AIDS has led to new efforts in the search for novel antifungal compounds. At the same time, there is continuing interest in the discovery of antifungal agents which are effective against plant pathogenic fungi. Since the plant kingdom provides a useful source of lead compounds of nov...

The Objective of this research was determination of antioxidant and antimicrobial activities of different plants of the families lamiaceae including several salvia species and some plants of the family Compositae e.g. Onopordon, Centaurea from Iran. The radical scavenging activities of the above-mentioned plants were measured spectrophotometrically using DPPH (2, 2 dipheny-pycryl-hydrazyl). The...

Chick embryo egg hydrolysates (CEEH) were obtained by enzymatic hydrolysis of chick embryo egg in vitro-simulated gastrointestinal digestion. The antioxidant activities of CEEH were investigated by employing three in vitro assays, including the 2,2'-azinobis-(3-ethylbenzthiazoline-6-sulfonate)/1,1-diphenyl-2-picrylhydrazyl (ABTS/DPPH)/hydroxyl radical-scavenging assays. The radical-scavenging e...
