Phytochemical Screening, Antibacterial and Antioxidant Activities of Ocimum basilicum L. Cultivated in Biskra, Algeria

Algerian flora contains a wide range of aromatic plants of great therapeutic interest thanks to their biologically active secondary metabolites which makes them a subject of scientific interest. In this work, we were interested in Ocimum basilicum L. of Lamiaceae family cultivated and harvested in Biskra city located at South-East of Algeria. Phytochemical screening has been per-formed to reveal the presence of flavonoids, tannins, coumarins, essential oil, and other phytochemicals. The contents of total polyphenols, total flavonoids and total tannins have been determined.

Synthesis, Characterization, Antimicrobial and Molecular Docking Study of Benzooxadiazole Derivatives

In this study, a series of new1,2,5-oxadiazole compounds derived from 4-chloro-7-nitro-benzo 1,2,5-oxadiazole was synthesized using different organic procedures. The resulting derivatives were chemically characterized and their structures were confirmed by FT-IR and NMR analysis. All the compounds were also evaluated for their antibacterial and antifungal activity against four types of pathogenic bacteria: S.aureus, S.epidermidis (as gram-negative bacteria), E.coli, Klebsiella spp. (as gram-positive bacteria) and the fungus Candida albicans using the agar well diffusion method.

Antibacterial Cellulose Acetate Microfibers Containing Pyridine Derivative Complexes

Pyridine (L1) and 2,4-dimethylpyridine (L2) halide complexes of the type of [ML2X2] were prepared and characterized via FT-IR and 1H NMR. The CA microfibers containing complexes were electrospun and investigated via FT-IR. The morphologies of the microfibers were investigated via FE-SEM. Antibacterial activities of the complexes and the fibers were investigated.

Synthesis of Tween-Coated Silver Nanoparticles by a Plasma-Chemical Method: Catalytic and Antimicrobial Activities

Stable silver nanoparticles were rapidly synthesized by simple, eco-friendly atmospheric pressure plasma method using non-ionic Tween 80 (polyoxyethylene-(80)-sorbitan monooleate) as capping agent. Influences of Tween 80 concentration on the formation efficiency of silver nanoparticle, their average size and stability have been studied. The synthesized silver nanoparticles had significant antibacterial activity on two strains of Gram bacteria.
