Microwave-assisted extraction of phenolic compounds from Moringa oleifera seed as anti-biofouling agents in membrane processes

Moringa seed has known as a coagulant in the water purification process. It is because of the large amount of anti-microbial compounds contained in it. Phenol is one of the most common anti-microbial compounds found in natural materials. The aim of this study was to determine the total phenolic content (TPC) of Moringa seed which was extracted by Microwave-Assisted Extraction (MAE). Moringa seeds were characterized by FTIR and showed that it contained phenol compounds confirmed by specific peak in some areas. Moringa seeds were characterized by FTIR before extracted. Therefore, MAE was performed by variation of solvent ratios (1: 4, 1: 6, 1: 8) and extraction time (2, 3, 4 min). The highest TPC of 41.78 mg GAE / g dw was reached at 1: 8 solvent ratio and 3-min extraction time
