The present study was to compare the Phytochemical and Antimicrobial analysis of W. somnifera and W. obtusifolia. In the Ethanolic leaf and root extract of Withania species were screened for phytochemical compounds by qualitative and FT-IR, UV method. Withania species have been used for remedies of human pathogen because they contain therapeutic compounds. This research work was mainly focused ...

N-[(1E)-(3-Bromophenyl)methylene]-N-(2-piperidin-1-ylethyl)amine Schiff base was prepared in good yield and characterized by the reflux of equivalent amounts of 2-(piperidin-1-yl)ethanamine with 3-bromobenzaldehyde. The structure of the desired Schiff base was analyzed based on: elemental analysis, EI-MS, TG/DTG, UV-visible, FT-IR, 1H and 13C-NMR spectral analysis. The condensation reaction was...

The exopolysaccharide (EPS) separated from the entomopathogenic fungus Metarhizium anisopliae was determined by gel permeation chromatography to be homogeneous. The high-performance anion-exchange chromatography with pulsed-amperometric detection (HPAE-PAD) showed a content of monosaccharides D-galactosamine and D-fucose at a molar ratio of about 2:1. The results obtained from Fourier transform...

This study aimed to evaluate the extract of chitosan obtained from pink shrimp (Parapenaeus longirostris) shell wastes in Balıkesir, Marmara Sea Turkey, and characterize its quality. The physicochemical properties biopolymer such as moisture content, solubility, degree deacetylation (DD), molecular weight (MW), particle size, bulk density, pH, water-binding capacity (WBC), fat-binding (FBC), co...

FT-Raman and FT-IR spectra of 5-methyl-2-(p-fluorophenyl)benzoxazole were recorded and analysed. The vibrational frequencies of the compound have been computed using the Hartree-Fock/6-31G* basis and compared with the experimental values.

this article presents the method of extraction-preconcentration of lead, cadmium, and nickel ions from food samples using the ghezeljeh montmorillonite nanoclay (geleh-sar-shoor) as a new native adsorbent in batch single component systems. the extraction-preconcentration of heavy metals were carried out by applying the solid phase extraction (spe) method followed by atomic absorption spectrosco...

Fourier Transform Infrared (FT-IR) spectroscopy is a robust method for macromolecular analysis and differentiation of microorganisms. However, most studies are performed in controlled conditions and it is unclear whether this tool is appropriate for the identification of eukaryotic microalgae species from variable environments. In order to address this, nine closely-related species of marine an...
