چکیده
Dioscorea hispida Dennst atau di Indonesia dikenal dengan umbi gadung diketahui mengandung senyawa aktif fenol yang dapat memberikan aktivitas antioksidan. Ekstraksi dari masih belum banyak diteliti. Tujuan penelitian ini adalah untuk mengekstraksi menggunakan metode ultrasonic-assisted extraction (UAE) pelarut bervariasi yaitu air, etanol, dan metanol serta menguji antioksidannya. Penentuan kandungan total (TPC) ekstrak secara kuantitatif telah dilakukan spektrofotometri uv-vis prinsip reaksi reduksi antara Folin–Ciocalteu asam galat. Pengujian antioksidan peredaman 2,2-difenil-1-pikrilhidrazil (DPPH). Dari bahwa paling tinggi terdapat pada sebesar 4,467 ± 0,752 gGAE/100 g terkuat dilihat nilai IC50-nya 4,395 μg/mL.
