In the liver, this process will cause impaired liver function. Oxidative stress can be inhibited by antioxidants. Arrowroot tubers (Maranta arundinacea) contains phenolic, flavonoid, alkaloids and saponin compound that are potential as antioxidants. Objective: Determine the effect of ethanolic extract of arrowroot tubers (Maranta arundinacea) against oxidative stress using the parameter of MDA, SGPT and SGOT level in ethanol-induced rats. Methods: Animal models were divided into 5 groups, in which each group contained 6 rats. Group I (normal) and group II (control) was induced with CMC Na 0,5%. Group III, IV and V were given ethanolic extract of arrowroot tubers in the dosage of 125, 250 and 500 mg/Kg/day respectively. The extract was administered orally for 14 days. Induction of ethanol 5 gram/ KgBW was administered orally 1 hour after the last administration on day 14th except for group I. On day 15th, the animal blood was drawn to measure the levels of SGPT and SGOT, then the animals were sacrificed and their organs were analyzed to measure the levels of MDA in the liver. Data obtained in the form of MDA, SGPT and SGOT levels were statistically analyzed using ANOVA. Results: There is statistically significant difference between the utilization of ethanolic extract of arrowroot tubers (Maranta arundinacea) group with the control group in reducing the concentration of MDA (p<0,05), SGPT, and SGOT (p<0,05). Conclusions: The ethanolic extract of arrowroot tubers (Maranta arundinacea) is able to reduce the concentration of MDA, SGPT and SGOT in ethanol-induced rats. Latar Belakang: Paparan radikal bebas akan menginduksi stress oksidatif. Pada organ hepar proses ini akan mengakibatkan terjadinya gangguan fungsi hati. Umbi garut mengandung senyawa fenol, flavonoid, alkaloid dan saponin yang berkhasiat sebagai antioksidan. Tujuan:Untuk mengetahui efek ekstrak etanol umbi garut terhadap stres oksidatif melalui parameter kadar MDA, SGPT dan SGOT. Metode: Hewan uji dibagi menjadi 5 kelompok, tiap kelompok terdiri dari 6 ekor tikus. Kelompok I (normal), kelompok II (kontrol) diberi CMC Na 0,5 % + induksi etanol, kelompok III, IV dan V diberikan ekstrak etanol umbi garut dengan dosis masing-masing 125, 250 dan 500 mg/KgBB/hari. Ekstrak diberikan secara oral selama 14 hari.Induksi etanol 5 gram/KgBB diberikan secara oral 1 jam setelah pemberian terakhir pada History: Received : May 27, 2016 Accepted : January 12, 2017 Online : April 26, 2017
