Tujuan penelitian untuk mengetahui efek antiulkus isolat fukoidan dan Sargassum polycystum terhadap tikus putih jantan. Sampel terdiri dari 45 ekor tikus jantan dibagi 9 kelompok yaitu normal, CMC-Na, sukralfat, fukoidan dan 25mg/kgbb, 50mg/kgbb dan 100mg/kgbb. Perlakuan diberi per oral selama 10 hari. Pada hari ke-10, tikus dipuasakan selama 24 jam dan diberikan induksi etanol P.A. Kemudian tikus dikorbankan dan diambil lambung untuk dilakukan pemeriksaan makroskopik dan mikroskop. Hasil pemeriksaan karakteristik simplisia Sargassum polycystum diperoleh kadar air 9,05%, susut pengeringan 8,74% dan rendemen hasil isolasi fukoidan dan adalah 4,01% dan 6,4%. Hasil identifikasi fukoidan secara spektrofotometri FTIR menunjukkan bentuk spektrum dan kurva serapan identik dengan baku pembanding fukoidan. Persentase jumlah tukak masing-masing dosis fukoidan dan yaitu, dosis 25mg/kgbb (1.04 dan 0,85), dosis 50mg/kgbb (0,84 dan 0,67), dosis 100mg/kgbb (0,21 dan 0,40). Kesimpulan hasil penelitian adalah isolat fukoidan dan memiliki efek gastroprotektif terhadap lambung tikus putih dengan dosis optimum 100mg/kgbb.
