Ultrasonic-Microwave-Assisted Extraction Process of Polysaccharides from Bombax ceiba

The yield of Bombax ceiba polysaccharide was selected as investigation index，through single factor combined with response surface methodology，influence factor and optimum process of ultrasonic-microwave-assisted extraction of polysaccharide from Bombax ceiba were discussed.Results showed order of influence factors of ultrasonic-microwave-assisted extraction process was microwave power＞extraction time＞solid-to-liquid ratio.Optimal ultrasonic-microwave -assisted extraction conditions were solid-to-liquid ratio of 1∶40（g/mL），extraction time of 16 min，and microwave power of 202 W，and at this condition，yield of Bombax ceiba polysaccharide was 0.953%±0.015%.In addition，compared with traditional water extraction，ultrasonic-microwave-assisted extraction methods improved yield of Bombax ceiba polysaccharide in a shorter time，which has broad application prospect.
