The potential of subcritical water extraction to recover steviol
glucosides from Stevia rebaudiana leaves was also studied.76 A
Box-Bhenken experimental design was used to evaluate the
effects of temperature (100−150 °C), extraction time (30−60
min), and flow rate (2−6 mL/min) at 230 bar pressure, and
using a solid/liquid ratio of 1/10 (m/v). The optimal extraction
conditions were found at 125 °C, 45 min, and 4 mL/min flow
rate. At these conditions, the yields of stevioside and
rebaudioside A were 38.67 mg/g and 35.68 mg/g, respectively
