摘要:

采用微波辅助热水提取法提取人参根茎和人参须中的多糖,通过正交试验,得到人参根茎粗多糖提取的最佳工艺条件为微波功率400W、料液比1:40g/mL、微波时间2min、浸提温度90℃、浸提时间2h,在此条件下最大提取率为19.86%。人参须中粗多糖提取的最佳工艺条件为微波功率400W、料液比1:30(g/mL),微波时间4min、浸提温度70℃、浸提时间2h,最大提取率为17.58%。人参根茎中的粗多糖的含量略高于人参须中的粗多糖。采用微波预处理后,人参多糖的提取率均高于传统热水提取法,证明采用微波辅助热水提取法提取人参多糖可行。

Abstract:

In this study, microwave-assisted hot water extraction was used to extract polysaccharides from ginseng roots and ginseng fibers. Using an orthogonal array design, the optimum microwave power, solid-to-liquid ratio, microwave time and extraction time were 400 W, 1:40 (g/mL), 2 min, 90 ℃ and 2 h for ginseng roots and 400 W, 1:30 (g/mL), 4 min, 70 ℃ and 2 h for ginseng fibers, respectively. Under the optimized conditions, the maximum yields of crude polysaccharide from ginseng roots and ginseng fibers were 19.86% and 17.58%, respectively, which were higher than those obtained by traditional hot water extraction.

Key words: ginseng root, ginseng fiber, polysaccharide, microwave
