Abstract

This study succinctly investigated the impacts of energy-based functions on the total phenolic and physicochemical characteristics of Euphorbia hirta. The results of the orthogonal experimental array gave an optimum microwave condition at 2 min of irradiation time, 400 W of microwave power, 12 mL/g of solvent loading, 40°C of the temperature level, and 50% of ethanol concentration. The results from the thermal stability curves revealed initial 89.96% weight retention (< 100°C) from moisture loss and the potential formation of sixty-six phenolic constituents from the disorientated microstructure (
