Piper nigrum L.: silver nanoparticles

Meer over het boek

The study explores the synthesis of silver nanoparticles (AgNPs) from Piper nigrum essential oil nanoemulsion, utilizing a phase inversion method and AgNO3 reduction. It highlights the chemical profile, with limonene as the primary component, and evaluates the antioxidant and anti-inflammatory activities of the AgNPs. Notably, the research found an IC50 value of 16.26 mg L-1 for antioxidant activity and 0.217 mg mL-1 for anti-inflammatory effects at pH 11, demonstrating the efficacy of P. nigrum AgNPs in enhancing these biological activities.
