EKSTRAKSI ANTIOKSIDAN DARI FULI PALA (Myristica fragrans) DENGAN METODE ULTRASONIC ASSISTED EXTRACTION

Abstract

Resa Shelomita. 102319083. ANTIOXIDANT EXTRACTION FROM MACE (Myristica fragrans) USING ULTRASONIC ASSISTED EXTRACTION METHOD. In this research, extraction tests were conducted using mace with ethanol as the solvent. Ethanol with concentrations of 96%, 80%, and 60% was used, each with ratios of 1:5, 1:10, and 1:15, respectively. The extraction was accelerated using the Ultrasonic Assisted Extraction method. The purpose of this extraction was to identify the antioxidant activity present in mace. Mace was dissolved with each ethanol concentration and ratio, then sonicated using a sonicator and dried in a vacuum oven, leaving only the extract. The resulting extract was characterized using FTIR, GCMS, UV-VIS, and antioxidant techniques. The characterized results indicated that mace contains phenolic compounds, which are utilized as antioxidants. The antioxidant test conducted showed a strong IC50 result of 140.6693 ppm, categorizing it as a strong antioxidant activity, indicating that mace contains antioxidant compounds.
