Abstract

Nipah fruit fibers (Nypa fruticans) contain bioactive compounds, namely polyphenolic compounds which function as antioxidant compounds. The bioactive compound content in nipah fruit fibers (Nypa fruticans) can be obtained through an extraction process. Extraction is the process of separating the various components present in a material and then extracting them using a certain type of solvent. This research aims to determine the effect of different solvents on the extraction of polyphenolic compounds from nipah fruit fiber (Nypa fruticans) as a natural antioxidant. This research was carried out experimentally in a laboratory using a Randomized Block Design (RAK) and the data obtained were analyzed using ANOVA and the Honest Significant Difference (BNJ) test. Extraction of polyphenolic compounds from palm fruit fibers (Nypa fruticans) consisted of 3 treatments with different solvents consisting of distilled water, 50% ethanol and 50% acetone. The parameters observed consisted of: extract yield, total phenolic content, total tannin content, total flavonoid content, antioxidant activity, and functional group analysis. The results of the research showed that different solvents had a significant effect on the total yield, total phenolic content, total tannin content, total flavonoid content, but had no significant effect on the antioxidant activity of nipah fruit fibers (Nypa fruticans). Extraction of polyphenolic compounds from palm fruit fibers (Nypa fruticans) with different types of solvents resulted in an average total yield of 14.19% sample to 14.65% sample, total phenolic content of 9.50 mg GAE/g sample to 40.09 mg GAE/g sample, total tannin content of 15.04 mg TAE/g sample to 51.45 mg TAE/g sample, total flavonoid content of 1.89 mg QE/g sample to 14.19 mg QE/g sample, Antioxidant activity testing with a concentration of 2 mg/mL sample was 62.42% to 87.70%, and there are O-H, C=C, C-H and C-O functional groups and does not have the C=O functional group. The 50% acetone solvent treatment was determined as the best treatment based on the results of total phenolic content, total tannin content, antioxidant activity, and had no significant effect on total yield. Keywords: antioxidants, extraction, different solvents, polyphenolic compounds, palm fiber
