Abstract

This study examines the potential compounds dragon fruit peel extract (Hylocereus polyrhizus) which are synthesized into silver nanoparticles, then used as the antiseptic mouthwash. The synthesis process is carried out using the Green Synthesis Nanoparticle method, which utilizes natural materials as metal bioreductants due to it is more herbal and does not have a poisonous effect on health. Secondary metabolite compounds contained in dragon fruit peel extract (H. polyrhizus), namely flavonoid compounds functioned by donating electrons to Ag+ ions to produce silver nanoparticles that can be used as mouthwash because they are antimicrobial. Based on the results of the UV-Vis spectrum, the best nanoparticle synthesis results were obtained at the extract concentration of 0.25% for 30 minutes duration with a synthesis temperature of 70°C, which the absorbance peak of silver nanoparticles was obtained at wavelength of 444.5 nm, and visually changes the color of the solution to brown. Furthermore, based on the test results obtained from incubation for 24 hours, it was found that the mouthwash solution showed an inhibition zone on the two test bacteria. Escherichia coli bacteria produced an inhibition zone of 28 mm, while Staphylococcus aureus bacteria produced an inhibition zone of 25.5 mm.
