Optimum Sample

The aim of the present study was to determine the proper concentrations of whey protein isolate (WPI), Arabic gum (AG), and Zedo gum (ZG) for the encapsulation of Nigella sativa seed oil (NSO). WPI, AG, and ZG were used as wall materials for the encapsulation of NSO by mixture design and then the optimum sample with minimum Z-average, PDI, and a* and maximum zeta potential, conductivity, encapsulation efficiency, and b* was selected for examining FT-IR and SEM. The findings demonstrated that lower particle size and particle dispersion index were obtained at higher amounts of AG and WPI with the least a*. Desirability function results indicate that the mixture of 39.05% WPI, 16.758% AG, and 4.192% ZG led to the production of the optimum sample. Microencapsulation of Nigella sativa seed oil using the optimum wall composition was recognized to be useful to preserve bioactive compounds and provide flavor stability, enabling the use of microcapsules in food formulations.

Black Cumin Seed Oil

Acne is a skin problem that often occurs, one of the causes is the bacterium Staphylococcus epidermidis. Black cumin seed oil (Nigella sativa L.) can be used as an antibacterial because it contains thymoquinone and α-pinene. This study aims to obtain black cumin seed oil emulgel preparations that has antibacterial activity against Staphylococcus epidermidis. The preparations were formulated with concentrations of 3% (FI), 5% (FII), and 7% (FIII). Evaluation of the preparation was carried out for eight weeks including organoleptic tests, spreadability, emulsion type, pH, viscosity, homogeneity. Antibacterial activity tests was carried out using the well-diffusion method. The results of the evaluation of all three formulas obtained showed a semi-solid consistency, light brown in color, characteristically smelled of black cumin seed oil, stable, M/A emulsion type, homogeneous, non-irritating, pH FI = 4.51-4.95, FII = 4.72-4.99, FIII = 4.57-4.87, dispersion FI = 3.2-3.8 cm, FII = 3.3-3.9 cm, FIII = 3.4-3.9 cm, viscosity FI = 10.7-26.1 Ns/m2, FII = 11.2-32.0 Ns/m2, FIII = 11.5-34.1 Ns/m2. The antibacterial activity test showed the inhibitory power of FI 11,66±0,09 mm, FII 14.48±0.03 mm, FIII 17.35±0,.8 mm, lower than the positive control (clindamycin). All three black cumin seed oil emulgel preparations obtained met the physical requirements and had bacterial inhibition (p

Silver nanoparticles were biosynthesized from Nigella sativa seed extracts using ethanol and chloroform. The antibacterial activity of silver nanoparticles against some drug-resistant bacteria has been established, but further study is needed to assess whether these particles could be an option for the treatment and prevention of drug-resistant microbial infections. Synthesized nanoparticles were characterized and screened for their antibacterial properties on resistant strains. The biosynthesized silver nanoparticles were characterized by UV-Visible, FTIR, Dynamic light scattering and Scanning Electron Microscope (SEM) analysis. The antibacterial action of biosynthesized silver nanoparticles was assessed by Microtitre Broth dilution process using Ciprofloxacin as standard, against resistant strains like Pseudomonas aeruginosa, Clostridium difficile, Klebsiella pneumoniae and Streptococcus pyogenes. The Silver nanoparticles obtained from chloroform extract of Nigella sativa seeds were more effective against Pseudomonas aeuruginosa, Clostridium difficile and Streptococcus pyogenes; than ethanolic seed extracts at 120 µL. Our data propose that the silver nanoparticles are effective against a variety of drug-resistant bacteria, which makes them a potential candidate for use in pharmaceutical products that may help to treat drug-resistant pathogens in different clinical environments. The present study focuses on the ability of phytoconstituents capped with silver nitrate can be used to treat infections caused by resistant bacteria
