中文摘要: 采用响应面法优化当归多糖的超声提取工艺。在单因素试验的基础上，以液料比、超声温度、超声时间为考察因素，采用Box-Beheken 设计试验方案，以多糖的提取率为评价指标。当归多糖的最佳提取工艺为：超声温度37 ℃、液料比20 ∶1（mL/g）、超声时间62 min。该条件下多糖提取率为8.63%
Abstract:The ultrasonic extraction process of Angelica sinensis polysaccharide was optimized by response surface method.On the basis of a single factor test，the ratio of liquid to material ，ultrasonic temperature，and ultrasonic time were the factors，The Box-Beheken was used to design test program.The extraction rate of polysaccharide was taken as the evaluation index.The best extraction process of Angelica polysaccharide is：Ultrasonic temperature 37 ℃，The ratio of liquid to material 20 ∶1 （mL/g），Ultrasonic time 62 min.The extraction rate of polysaccharide was 8.63%.
