【摘要】 以宣木瓜为原料,采用超声波法正交试验设计优化提取其中的多糖,研究不同料液比、超声时间、超声温度和超声功率对宣木瓜多糖提取效果的影响,结果表明;在料液比为1:40(g/mL),超声时间45min,超声温度80℃,超声功率400W时宣木瓜多糖的提取率最高;宣木瓜多糖的最佳提取率为10.61%,优化提取条件可使宣木瓜多糖的提取率提高3.24倍。更多还原

【Abstract】 The optimum extracting conditions of polysaccharide from Chaenomeles speciosa with ultrasonic were studied by the orthogonal test design. The effects of different material liquid ratio,ultrasonic time,ultrasonic temperature and ultrasonic power on the extraction of polysaccharide from Chaenomeles speciosa were investigated. When the ratio of liquid was 1:40(g/mL),ultrasonic time was 45 min,ultrasonic temperature was 80 ℃ and the ultrasonic power was 400 W,the extraction rate of polysaccharide was the highest,the optimum extraction rate of polysaccharide was10.61%,and the extraction rate of polysaccharide was improved by optimizing the extraction conditions.更多还原
