Identifikasi dan Uji Penangkapan Radikal 2,2 Difenil-1-Pkrilhidrazil (DPPH) dari Ekstrak Kasar Pigmen Bakteri Simbion Rumput Laut

Abstrak Seaweed belongs to the group of natural antioxidants, these antioxidants are able counteract free radicals. Secondary metabolites that include alkaloids, flavonoids, phenolic compounds, steroids, and terpenoids carotenoids. This study aims identify test radical scavenging 2,2 diphenyl-1-pkrylhydrazyl (DPPH) from crude extract macroalgae symbiont pigment Turbinaria conoides originating coastal waters Hamadi Jayapura, Papua. The method used in this is an experimental by identifying pigments using Thin Chromatography (TLC), for Antioxidant testing DPPH Method. results TLC plate Spot 1 on yellow plate, which had a Retardation frequency (Rf) value 5/8 = 0.62 was identified as carotenoid. TC.11 bacterial also has antioxidant potential tested method. See IC50 bacteria 24315 ppm compared β-carotene marker 4103
