Ultrasonic-assisted Extraction of Total Polyphenol from Seeds of Syzygium jambos by Response Surface Methodology
Objective:To optimize the ultrasonic-assisted extraction process of total polyphenol from Seeds of Syzygium jambos. Method: Response surface- analysis was conducted for optimizing the main technical parameters with the content of total polyphenol as index, and received the regression model. Result:The best parameters were as follows: the ratio of liquid to material was 47: 1 (mL: g) , ethanol concentration was 38% , ultrasonic extraction time was 32 min. Under this conditions, the extraction yield of total polyphenol was 16.32%. Conslusion: The relative error was 0. 7% between the regression model predicted and measured by response surface method, the regression equation fitted well with the actual situation.
