摘要
柳蒿芽是长白山地区常见的药食同源植物,活性成分多样.为了优化柳蒿芽多糖的超声波提取过程,本研究采用响应面法(RSM)进行实验设计和数据分析,探究了料液比、提取温度、提取时间、超声功率这四个因素对柳蒿芽多糖得率的影响,并优化确定了柳蒿芽多糖的最佳提取工艺.结果表明:在料液比(mg/L)1:78、提取温度78 ℃、提取时间62 min、超声功率400 W条件下,多糖得率达28.9％.超声波法提取柳蒿芽多糖具有快速、高效和环境友好的特点,为今后柳蒿芽多糖的应用研究提供理论基础和指导.
Abstract
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..
