Ultrasonic extraction of polysaccharides from Artemisia integrif olia L.and optimization of its process
Artemisia integrifolia L.is a common medicinal and edible plant in the Changbai Mountain region,with a wide range of active compounds.In order to optimize the ultrasound-assisted extraction process of polysaccharides from Artemisia integrifolia L.,this study used re-sponse surface methodology(RSM)for experimental design and data analysis.The effects of four factors,namely solid-liquid ratio,extraction temperature,extraction time,and ultrasonic pow-er,on the yield of polysaccharides were investigated,and the optimal extraction conditions for the polysaccharides from Artemisia integrifolia L.were determined.The results showed that under the conditions of a solid-liquid ratio of 1:78 mg/L,extraction temperature of 78 ℃,ex-traction time of 62 minutes,and ultrasonic power of 400 W,the polysaccharide yield reached 28.9％.Ultrasound-assisted extraction of polysaccharides from Artemisia integrifolia L.as the advantages of rapid extraction,high effi-ciency,and environmental friendliness,providing a basis and guidance for the application research of polysaccharides from Artemisia integrifolia L..
