响应面法优化当归多糖超声提取工艺研究

Optimization of Ultrasound Extraction Technology of Angelica sinensis Polysaccharide by Response Surface Methodology

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%。

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 %.
