Using subcritical water (temperature and pressure of higher than 100 ºC and 1 atm) polarity of water changes into the organic solvents which that can be easily used in extraction of the valuable components from the plant sources. In the present study, simulation of the operation conditions for saponin extraction from the Chubak and using subcritical water was accomplished. Results indicated that by placing the of autoclove in the oven adjusted at temperatures of 120, 140, 160, 180 and 200 ºC, after 120 min the international temperastures of the water inside the autoclove were 107, 124, 144, 161 and 178 ºC, respectively. Saponin extraction was done using water at 130 ºC and 120 min and the result indicated that the water inside of autoclove had temperature of 116 ºC, which that was in subcritical state. The result revealed that lipid content of Chubak was 3% (W/W). Furthermore, extraction results indicated that the foaming height and emulsification capacity of the extracted sample using subcritical water were 2.7 and 1.5 folds higher than those of the extracted sample using water.
