Kinetic Extraction of Moringa Oleifera Leaves using the Microwave Assisted Extraction (MAE) Method

Abstract

Moringa leaves (Moringa oleifera) are part of a plant that has a leaves-like shape with various high health and nutritional benefits, and contains vitamins, minerals, proteins and bioactive compounds, and has antioxidant and anti-inflammatory properties. This research aims to study extraction, determine the presence of tannin content in Moringa leaves and determine the kinetic model of extraction of Moringa leaves extract yield using the Microwave Assisted Extraction (MAE) method. The Moringa leaves extraction process is carried out using 96% ethanol solvent and using the MAE method which can help maximize the extraction yield. The extraction process was carried out with varying power of 150 watts, material to solvent ratio of 1:15 b/v and extraction times of 2, 4, 6, 8 and 10 minutes. The research results showed that the highest yield value was obtained at the 10th minute extraction time, namely 10.25%. The extraction kinetic model that is suitable for extracting tannin compounds from Moringa leaves is order 2, where the R2 0.9897 valuen is higher than order 1 and the value is almost close to 1.
