Abstract

Umbi bawang dayak (Eleutherine palmifolia (L.) Merr.) memiliki kandungan fenol dan flavonoid yang berkhasiat sebagai antioksidan. Kandungan kimia dalam suatu tumbuhan dapat dipengaruhi dengan adanya proses pengolahan bahan baku. Salahsatu proses pengolahan baku tumbuhan yaitu dengan adanya fermentasi menggunakan pemanasan. Penelitian ini bertujuan mengetahui pengaruh fermentasi pada kandungan kimia dan aktivitas antioksidan pada ekstrak umbi bawang dayak. Penelitian ini dilakukan dengan fermentasi umbi bawang dayak dengan pemanasan selama 10, 20 dan 30 hari. Ekstraksi dilakukan menggunakan maserasi dengan pelarut etanol 70%. Penetapan kadar fenol total, flavonoid total dan aktivitas antioksidan menggunakan spektrofotometer UV-Vis. Hasil penelitian menunjukkan, ekstrak umbi bawang dayak hasil fermentasi selama 30 hari memiliki kadar fenol total, kadar flavonoid total dan aktivitas antioksidan tertinggi, ditunjukkan secara berurutan (3,721 g GAE/100 g ekstrak ± 0,210; 0,378 g QE/100 g ekstrak ± 0,189, IC50 peredaman DPPH 28,689 µg/mL± 0,144). Adanya proses fermentasi dan lama proses fermentasi dapat mempengaruhi kandungan kimia dan aktivitas antioksidan ekstrak umbi bawang dayak.

Abstract

Mangosteen (Garcinia mangostana L.) is known as a plant rich in antioxidants and has various pharmacological activities. This study aims to determine the activity of the ethanolic extract of G. mangostana L. to decrease mercury levels in the kidneys. Mangosteen rind was extracted using 96% ethanol using the maceration method to form a thick extract. The experimental animals used in this study were Swiss Webster strain mice which were grouped into normal group (CMC suspension 0.5%), negative control (induction of HgCl2 solution), positive control (induction of HgCl2 solution followed by administration of curcumin at a dose of 100mg/KgBW). , and the test group was given mangosteen peel extract at a dose of 200mg/kgBW, 400mg/kgBW, 600mg/kgBW. In the test group, mice were induced using HgCl2 for 14 days, followed by administration of ethanol extract of mangosteen rind for 24 days. Observations were made with kidney organ surgery and observations were made using Atomic Absorption Spectrophotometry (AAS) and analyzed using ANOVA. The test results showed mercury accumulation in the negative, positive control group, and the test doses of 200, 400 and 600mg/kgBW, respectively, were 44.3mg/kg, 7.3mg/kg, 36.46mg/kg, 35.7mg/kg. kg and 31.34mg/kgBW with an effective dose of 600mg/KgBW.
