- Abstract
Moringa oleifera leaves are rich in nutrients and bioactive compounds such as polyphenols which can be used as an antioxidant. Polyphenols of Moringa leaves can be extracted using conventional and non-conventional methods. This study compared maceration with Pulsed Electric Field (PEF) pretreatment and MAE method on extracting polyphenols from Moringa leaves. The performance of those methods was assessed based on the yield extracts, total polyphenol content (TPC), and antioxidant activity (IC50). The results showed that different methods significantly affected TPC and antioxidant activity. Maceration with PEF pretreatments obtained extracts with the highest TPC value (179.11 mg GAE/g) and antioxidant activity (33.56 ppm). In comparison, the MAE method produced TPC and antioxidant activity values of 22.64 mg GAE/g and 54.59 ppm, respectively. The yield extracts did not show differences significantly. Maceration with PEF pretreatment and MAE obtained the yield extract of 12.62% and 13.16%, respectively. Based on the results, it can be seen that maceration with PEF pretreatment has a better ability to increase TPC and antioxidant activity compared to the MAE method. Maceration with PEF pretreatment can increase TPC up to 7.9 times and antioxidant activity up to 1.6 times.
