Optimization of Ultrasonic Extraction Process by Response Surface Methodology of Polysaccharides from Limonium bicolor Kunze (Bge.)

Abstract:

Polysaccharide from Limonium bicolor Kunze (Bge.)(LBPs) was extracted with the assistance of ultrasonic.Box-Behnken design(BBD) was employed to optimize extraction time; extraction temperature;ultrasonic extraction power and ratio of water to raw material to obtain a high LBPs yield.The optimum extraction conditions were as follows: extraction temperature 81.23°C, ultrasonic power 190.86W, extraction time 42.39 min and ratio of water to raw material 15.4ml/g.The yield of polysaccharide was 7.11% based on the above mentioned conditions. Close agreement between experimetal and predicted values was found.
