In vitro antioxidant and anticholinesterase activities and in vivo toxicological assessment (Zebrafish embryo model) of ethanolic extracts of Capsicum chinense Jacq.

The ripe and dried fruits of organic pepper Capsicum chinense Jacq., obtained during planting, cultivation and harvesting, were subjected to solid-liquid extraction using a Soxhlet apparatus with hexane to remove non-polar compounds, and then with ethanol to remove the target compounds. The ethanolic extracts were characterized by gas chromatography-mass spectrometry (GC-MS) determining the composition of capsaicin...

Bioactive properties of some selected Libyan plants

The present work evaluates the antioxidant and antibacterial activities of four Libyan plants (Arbutus pavarii, Pegnanum harmal, Pistachia atlantica, and Fagonia bruguieri) using various assays including reducing power, Phosphomolybdenum, 1,1-diphenyl-2-picrylhydrazyl (DPPH)  and nitric oxide free-radical scavenging activity. In vitro, the antibacterial activity of crude and flavonoids extracts were determined...
