UJI AKTIVITAS ANTIOKSIDAN DAN PENETAPAN KADAR FENOLAT TOTAL FRAKSI AIR DAUN KETAPANG (Terminalia catappa L.) DENGAN METODE DPPH (2,2-diphenyl-1-picrylhydrazyl) DAN METODE FOLIN-CIOCALTEU
Abstract: The aqueous fraction of methanolic extract of Ketapang (Terminalia catappa L.). was investigated for its DPPH (2,2-diphenyl-1-picrylhydrazyl) free radical scavenger activity and the total amount of phenolic using Folin-Ciocalteu method. It was found that the aqueous fraction of methanolic...

| Summary: | Abstract: The aqueous fraction of methanolic extract of Ketapang (Terminalia catappa L.). was investigated for its DPPH (2,2-diphenyl-1-picrylhydrazyl) free radical scavenger activity and the total amount of phenolic using Folin-Ciocalteu method. It was found that the aqueous fraction of methanolic extract of Ketapang tested showed significant DPPH free radicalscavenging with IC50 value 34,071 ± 0,424 µg/mL. The total phenolic amount was 5.429 ± 0.110 mg equivalent mass value of gallic acid per gram aqueous fraction of the methanolic extract of ketapang leaves. Keywords: aqueous fraction, methanolic extract, Terminalia catappa, DPPH, total phenolic. |
