Abstract
Microwave-Assisted Extraction of phenolics compounds from soursop-peel (Annona muricata L.) was conducted at a fixed microwave power of 420 W with ethanol as the solvent of varying concentration (50%, 70%, and 96%) and extraction time (3 min, 5 min, and 7 min). The highest total phenolic content value was 2.37 mgGAE/gr of dried soursop-peel and was obtained at an extraction time of 7 min with an ethanol concentration of 96%. At this optimum parameter combination (7 min, 96%), the IC50 value of the extract was 78.05 μg/mL and classified as a strong antioxidant. While the Sun Protection Factor value was only 22.71 and it is categorized as having a fair-sun protection capability. The extraction time plays critical role on the contact time between solvent and the solid. Increasing extraction time from 3 minutes to 7 minutes in extraction using 96% ethanol, increased the TPC yield to more than 100%. While the increase of ethanol concentration from 50% to 96% only increase the TPC content by only 45 – 55%.
