FRAP REDUCING ACTIVITY OF PROTIUM JAVANICUM BURM.FIL LEAVES: A SCREENING ANTIOXIDANT POTENCY OF NATURAL COSMETIC INGREDIENT

Abstract

Tenggulun (Protium javanicum Burm.fil) has been traditionally used to treat various ailments such as cough, stomachache, diarrhea, inflammation and headache. The leaves have therapeutic roles in the treatment and prevention of illnesses acting as antibacterial, antidiabetic and antiinflammation agents. It is also reported that tenggulun leaves can be used for insecticides, cosmetics and food additives. This research aimed to determine antioxidant activity by reducing FRAP of the tenggulun leaves methanol extract using Trolox as the standard solution. The result showed that the tenggulun leaves extract contained secondary metabolites of flavonoid and polyphenolic. The extract showed the FRAP reducing activity at 0,008634±0.00043 μmol TE/g DW. These results indicated the ability of tenggulun methanolic extract to reduce Fe (III) into Fe (II) equivalent to Trolox by the presence of secondary metabolites confirmed.
