微波辅助提取山茱萸多糖的工艺研究

Study on Microwave-assisted Extraction of Polysaccharides from Corni Fructus

采用单因素试验和正交试验,进行了微波辅助提取山茱萸多糖的研究,得到了微波辅助提取山茱萸多糖的最佳工艺条件是料液比为1∶25(m/V,g∶mL),微波功率为560 W,微波处理时间为10 min,浸提时间为70 min。在此工艺条件下,多糖平均提取率为10.53%。与热水浸提法进行比较,微波辅助提取能缩短提取时间,提高山茱萸多糖提取率。

Microwave-assisted exaction（MAE）of Corni Fructus polysaccharides was studied by single factor design and orthogonal test.The results show that the optimum conditions of extraction were microwave treatment for 10min at power of 560W after being extracted for 70min,with the ratio of material to water at 1∶25（g∶mL）.Under these conditions,the yield of polysaccharides was 10.53%.MAE could shorten the exaction time and improve yield of Corni Fructus polysaccharides compared with direct hot water extraction.
