The percentage inhibitions for DPPH assay for ethanol leave extract, methanol leave extract, water leave extract, methanol seed extract, and methanol pod extract were 89.33, 84.05%, 74.85%, 89.09%, and 86.36%, respectively. antioxidant activity phenolic contents the highest value of total The antioxidant activity of the crude products was tested by the ABTS method showing of 40.82% for ethanol extract of the leaves. The ferric-reducing antioxidant power of the crude extract was tested by the FRAP technique to give the ability to reduce Fe3+ to Fe2+ of 7,581.60 mg g1 of the crude extract. The ethanol leaves extract provides the of 49.21 mg GAE g1. The percentages of tyrosinase inhibition activity of ethanol extract of the leaves showed the highest activity of 86.12%. The preliminary findings reveal that ethanol the leaves ethanol extracts have the potential to be used as a natural skinwhitening agent in cosmetic products. In this study, the ethanol leaves extract can be applied as an ingredient in cosmetic products including soap, facial cleansing gel, and cream formulated from the ethanol leaf extract of Moringa. Moreover, the Moringa soap product already passed the specification recommended by the food and drug administrations.</p> ER -
