- W2783404493 abstract "Present research was to evaluated the antioxidant activities of extracts from macroalga Sargassum sp. In this study, seven filtrates from maceration (methanol pa and technical grade, ethanol pa and techinal grade, methanol technical grade 50%, infused hot water, boiled water) were analyzed for total phenolic compound (TPC) and for antioxidant activities (DPPH method). The results revealed that the water filtrates possessed more TPC and antioxidant antivity than alcoholic filtrates, and the highest was water filtrate from boiled Sargassum sp. (TPC =1,36±0,01 mgGAE/g dry weight; % inhibtion DPPH = 81,35±0,42 %). The high positive correlation between TPC and antioxidant activity (r = 0.99 ) suggested that phenolic compound were the mayor antioxidant components. The effect of TPC (dependent variable) on DPPH radical inhibition (independent variable) with regression formula y = 55,39 x + 5,18. Keywords : Sargassum sp., phenolic compound, antioxidant activity. Penelitian ini mengevaluasi potensial aktivitas antioksidan ekstrak Sargassum sp. Pada kajian ini, 7 filtrat hasil maserasi (metanol pa dan teknis, etanol pa dan teknis, metanol teknis 50%, perendaman air panas/hot infused, dan perebusan dengan air) dianalisis kandungan total fenoliknya (TPC) dan aktivitas antioksidannya (metoda DPPH). Hasil penelitian ini mengungkapkan bahwa filtrat air memiliki kandungan TPC dan antioksidan yang relatif lebih tinggi dibanding filtrat alkohol dan yang tertinggi adalah filtrat hasil perebusan Sargassum sp. (TPC =1,36±0,01 mgGAE/g berat kering; inhibisi DPPH = 81,35±0,42 %), Korelasi positif yang tinggi antara TPC dan aktivitas antioksidan (r = 0.99) menunjukkan bahwa kandungan senyawa fenolik merupakan komponen utama yang menghasilkan aktivitas antioksidan. Pengaruh TPC (variabel bebas) terhadap inhibisi radikal DPPH (variabel terikat) sesuai dengan persamaan regresi y = 55,39 x + 5,18. Kata kunci : Sargassum sp., senyawa fenolik, aktivitas antioksidan." @default.
