中文摘要: 采用微波辅助提取法从枸杞中提取枸杞多糖。以粗多糖得率为量化指标,利用单因素试验和正交试验设计法优化枸杞多糖的微波最佳提取工艺为:料液比1∶20(g/mL)、温度85℃、微波时间45 min、微波功率200 W。粗多糖的最终得率可达到7.22%。
Abstract:Single factor experiment and orthogonal experiment design was used to optimize microwave extraction of polysaccharide from Lycium barbarum,to put the polysaccharide yield as a evaluation index.Results showed that the best extraction conditionsas flows:the highest yield(7.22%)of the polysaccharide was obtained under 200 W of microwave power for 45 minutes at solid-solution rate of 1∶20(g/mL)at 85℃.
