微波提取红豆杉枝叶中多糖的工艺研究

摘要

在单因素实验的基础上，采用Box-Behnken中心组合实验和响应面分析法，优化了皖南红豆杉枝叶中多糖的微波提取工艺。研究了提取时间、微波功率、料液比和浸泡时间对红豆杉枝叶多糖提取率的影响，建立了影响因素与响应值之间的数学模型，确立最佳提取工艺。结果表明：皖南红豆杉枝叶中多糖的最佳提取工艺为：微波提取6.11 min，液料比为30砄1，浸泡时间为119.21 min，微波功率为6 kW。该方法为提高皖南红豆杉枝叶中多糖成分的提取提供了基础。%The study aimed to get optimized craft of polysaccharide extraction from Taxus wallichiana var.mairei in Southern Anhui in China.On the basis of single-factor experiments, then using Box-Behnken design and its response surface analysis , the main factors of extraction time , power of microwave , the ratio between solvent and material and soaking time affecting the extraction , effects of saccharide were studied and mathematical model between the response value and factors was established.The optimal craft was as follows:30 times of water , extracting 6.11 min by 6 kW power of microwave.The design and results provided the theoretical foundation of production process .
