摘 要:目的:采用中心组合(Box-Behnken)设计优选南方红豆杉[Taxus mairei(Lemee et Levl.)S.Y.Hu ex Liu]枝条中多糖的微波提取工艺。方法:在单因素实验基础上,采用Box-Behnken设计对影响南方红豆杉枝条中多糖提取率的主要因素(料液比、提取时间、提取次数)进行优化,建立影响因素与响应值之间的数学模型,确定最佳超声提取工艺条件。结果:南方红豆杉枝条中多糖最佳超声提取工艺为:料液比21.48(V/W),提取时间13.78 min,提取次数3次,微波频率为1887MHz。结论:采用响应面法对南方红豆杉中多糖的提取条件进行优化,该方法合理可靠,能为生产工艺提供理论依据。Objective : The Box - Behnken was selected to optimize the extraction technology of polysaccharides from the branches of Taxus mairei ( Lemee et Levi. ) S. Y. Hu ex Liu. Method: Based on the single factor experiment, the main elements ( the ratio between liquid and solid, the extractive time and times) affecting the extraction rate of polysaccharides from the branches of Taxus mairei( Lemee et Levi. ) S. Y. Hu ex Liu were optimized by using response surface analysis, and the functional relationship between the response value and elements was established. Result : The result of the experi- ment showed the optimal extraction conditions were as follows :21.48 times of water, extracting 13.78 min by 1887 MHz microwave frequency,3 times. Conclusion: It is feasible and reliable to optimize the conditions of extracting the polysac- charides from the branches of Taxus mairei (Lemee et Levl. ) S. Y. Hu ex Liu by response surface analysis which lays the theoretical foundation to its production process.
