摘要
目的:考察金钗石斛多糖的最佳提取工艺。方法:应用微波辅助提取技术,采用单因素试验和正交试验,以多糖的提取率为评价指标,对影响石斛多糖提取工艺的因素进行研究。结果:金钗石斛多糖最佳提取工艺为:微波频率为1470MHz,加30倍量水,浸提3h,微波10m in,在此条件下,金钗石斛粗多糖得率为4.23%。结论:金钗石斛多糖的提取中,微波辅助提取具有提取时间短、提取率高的优点。
Objective ： To optimize the process of extracting polysaccharides from D. nobileLindl. Methods ： Consider the extraction rate of polysaccharides as an examinable target, the optimal extraction conditions of polysaccharides has been proposed by microwave - assisted method through single factor experiment and orthogonal test method. Results ： The optimal conditions of extracting polysaccharides from D. nobileLindl, were： microwave power 1470MHz,30 of ratio of liquid to solid,3 hours of extracting time, 10 min of microwave heating time. The highest extraction ratio 4.23% Conclusion： The microwave - assisted extractive technique has the advantages of timesaving, high performance in the process of extracting polysaccharides from D. nobileLindl.
