Conclusion The results of this work demonstrated the differential antimicrobial activities of MESf and its alkaloid isolate, canthin-6-one with antibacterial and antifungal activities, respectively. The present study support the popular use of Simaba ferruginea in combatting afflictions related to bacterial infections, and demonstrate that canthin-6-one as a promising antifungal agent. Both MESf and canthin-6-one are considered non-toxic based on the in vitro toxicological study. Graphical abstract

Most heavy metal-based catalysts for degradation of aqueous organic pollutants in heterogeneous Fenton-like processes suffer from the toxicity of leached metals. The present work reports environmentally benign systems for both degradation of organics and bacterial disinfection. Calcium substituted LaFeO 3...

In this study, nanoemulsions were obtained by high pressure homogenization and ultrasonication using capsaicin (oleoresin capsicum) (2 g/100g) in the oil phase and Tween 80 (2 g/100g), glycerol (0-50 g/100g) in the aqueous phase at pH 7.4 and 3.8. Mean droplet sizes below 65 nm were obtained with ultrasonication. Translucent nanoemulsions with minimum 79% efficiencies were obtained with high pressure homogenization. Pressurized nanoemulsions reduced Staphylococcus aureus and Escherichia coli population up to 5.89 and 2.79 log respectively at pH 7.4. The addition of glycerol resulted in almost transparent, bright re...

Ashmawy, A.Z.M. Salem The aim of this work is to identify the chemical constituents and the bioactivity of essential oil (EO), acetone extract (ACE) and n-hexane extract (HexE) of S. terebinthifolius ripened fruits using GC-MS. Total phenolic content and antioxidant activity of extracts were determined using the Folin-Ciocalteu and 1,1-diphenyl-2-picryl-hydrazyl (DPPH) assays, respectively. The toxicity against the growth of Acinetobacter...

Fomites are reservoirs of drug-resistant pathogens found in the unhygienic clinical environment, which can infect patients and leading to high nosocomial infection rates and use of antimicrobial drugs. The use of and search for drugs and dietary supplements derived from plants have accelerated various therapeutic app...

This study aims at identifying the composition of polyphenols present in Amygdalus pedunculata Pall seed coat (APSC), and characterizing their antioxidant, antibacterial, and anticancer activities. The polyphenols from APSC were composed of 32 compounds. The compounds with important biological activities included apigenin 7-O-glucoside (the main component; 34.53 mg/100 g), quercitrin (23.43 mg/100 g), kaempferol (10.28 mg/100 g), naringenin (6.27 mg/100 g), cyanidin 3-rutinoside (5.76 mg/100 g), cyanidin 3-O-galactoside (5.19 mg/100 g), and quercetin (2.50 mg/100 g), as well as a variety of phen...

Chehimi The efficacy of surfactants in stabilizing CuO-NPs onto the surface of the cotton fibers and their ability to produce homogeneous CuO-coated cotton composite was studied using different types of surfactants. The use of surfactants provides better adhesion of the CuO NPs and consequence, enhanced its coating stability during exploitation. The optical structure and morphology of the coated cotton fabrics were examined by sev...

Al-blewi, Praveen K. Sahu, Mohamed R. Aouad The discovery of a novel series of task-specific fluorinated pyridinium ionic liquids (TsILs) tagged with Schiff bases is reported using ultrasound-assisted and conventional syntheses. The synthesis required the quaternization of the appropriate pyridine Schiff base, followed by the metathesis of the resulting task-specific halogenated pyridinium ILs. The structures of the ILs were establi...
