Abstract:

The response surface methodology based on Box-Behnken design principle was used to optimize processing parameters of ultrasonic and microwave extraction for polysaccharides from Acanthopanax sessiliflorus fruits. Results showed that the optimal processing conditions of ultrasonic extraction were material-liquid ratio of 1:70 (g/mL), ultrasonic power of 175W, extraction temperature of 60 ℃ and extraction time of 50 min. The optimal processing conditions of microwave extraction were material-liquid ratio of 1:40 (g/mL), microwave power of 595 W and extraction time of 80 s. The yields of polysaccharides were up to 3.491% and 3.482% under the optimal ultrasonic and microwave extraction conditions, respectively, which was consistent with the predicted results.

Key words: Acanthopanax sessiliflorus, polysaccharide, extraction, response surface methodology
