The effect of A & B: ethanol concentration (at fixed variables of solvent-to-solid ratio,S/S: 30 mL/g, power: 300W, time:2 min, and temperature: 65 °C) and C & D: S/S ratio (at fixed variables of ethanol concentration: 60%, power: 300W, time:2 min, and temperature: 65 °C) on TPC and DPPH radical scavenging activity of ME. Values are mean ± SD of triplicate analysis; Means with different letters denote significant differences of TPC and DPPH values within ranges of ethanol concentrations and within ranges of S/S ratio.
