Study on ultrasonic assisted extraction of polysaccharide from Angelica Dahurica
View through CrossRef
Taking Bozhou Angelica dahurica as the raw material, taking the polysaccharide yield as the evaluation index, the ultrasonic-assisted extraction of Angelica dahurica polysaccharide was studied. The effects of ultrasonic power, ultrasonic treatment time, solid-liquid ratio and temperature on the polysaccharide yield were investigated. Based on single factor experiment, the orthogonal experiment was carried out to optimize it. The results showed that the optimum technological conditions were as follows: solid-liquid ratio of 1:40, ultrasonic power of 500 W, ultrasonic time of 45 min, and the highest yield of Angelica dahurica polysaccharide was 15.8%. Ultrasonic time has a significant effect on the yield of Angelica dahurica polysaccharide. The ultrasonic power and the ratio of material to liquid have a significant effect, and the temperature has a low effect on polysaccharide extraction.
