Abstract :

The purpose of this study was to determine the effect of adding nanogold and nanosilver with various concentrations on the antioxidant activity of herbal medicine made from black seed, black garlic extract, and propolis. The concentration of nanogold used was 5,10,15,20,25 and 30 ppm with 20 ppm nanosilver concentration. In this study, the activity of antioxidant compounds was tested using the DPPH method with a UV-Vis spectrophotometer. This study shows the percentage of free radical reduction results. The results of this study indicate that there is an effect of adding nanogold in the antioxidant content of herbal medicines. The best nanogold concentration was shown at a concentration of 30 ppm, which was 84,42%. The results show that the greater the concentration of nanogold added, the greater the percent reduction.
