| Abstract | Ultrasonic-assisted extraction of gamma-aminobutyric acid (GABA) from mulberry leaves was investigated by response surface methodology (RSM) using central composite design and a numerical optimisation technique. Effects of extraction time (0-60 min.), ethanol solvent concentration (30-80%) and ratio of solvent to mulberry leaf powder (5-20 mL/g) on GABA content were studied with ultrasonic wave frequency fixed at 35 kHz. Optimised conditions for GABA extraction at 450.36 3.50 mg/100 g dry leaf powder (R2 = 0.9645) were extraction time of 60 min., ethanol concentration of 54.75% and ratio of solvent to mulberry leaf powder of 20 mL/g. |
