نویسندگان
چکیده
Kabupaten Brebes merupakan salah satu wilayah penghasil rumput laut di provinsi Jawa Tengah dengan luas tambak sebanyak 4.350 ha dari total sebesar 12.748 yang menghasilkan 200 ton kering per bulan. Rumput dapat digunakan sebagai sumber antioksidan karena mengandung senyawa bioaktif terutama untuk golongan fenolik, flavonoid dan alkaloid. Tujuan penelitian ini adalah mengkaji aktivitas fenolik bubuk Gracilaria sp. kabupaten Brebes. Parameter diamati yaitu kapasitas penangkapan radikal bebas menggunakan metode radical scavenging activity (RSA) DPPH Folin-Ciocalteu. Penelitian rancangan acak lengkap (RAL) terdiri dua perlakuan (bubuk bahan baku segar kering) dilakukan tiga kali pengulangan. Bubuk memiliki kandungan fenol lebih tinggi dibandingkan kering. Kandungan sekitar 4,35–4,49 (mg GAE/100 g) antioksidannya 15,90–42,50 (%RSA). Terdapat perbedaan basah

متن کاملDifferent regulation of haloperoxidation during agar oligosaccharide-activated defence mechanisms in two related red algae, Gracilaria sp. and Gracilaria chilensis.
The related red seaweeds Gracilaria sp. from the eastern Mediterranean and Gracilaria chilensis from Chile were similar in their enzymatic inventory for halogenation. In both species, halogenation was dependent upon H(2)O(2) and thus driven by haloperoxidases. These could be inhibited with phosphate and reversibly inhibited with azide and were therefore apparently dependent upon vanadate. Both ...
