摘要: 采用闪式提取法对黄芪主要活性成分进行提取,对提取工艺进行优化。以多糖、黄酮、皂甙作为测量指标进行单因素试验,并在此基础上设计L9(33)正交试验以对提取工艺进行优化。结果表明:闪式提取法提取黄芪中活性成分的最佳工艺条件是料液比1:20(g/mL)、提取电压120V、提取次数3次(每次1min),在此条件下黄芪多糖、黄酮和皂甙的得率分别为3.728%、0.135%、1.019%。该工艺提取时间短、提取效率高,是一种高效节能的新型黄芪活性成分提取方法。

Abstract: The extraction of functional components from Radix Astragalus by the flash extraction method was optimized using one-factor-at-a-time experiments followed by an L9(33) orthogonal array design based on the extraction yields of polysaccharides, flavonoids and saponins. The optimal extraction conditions were extraction at a solid-to-liquid ratio of 1:20 and 120 V voltage repeated 3 times for 1 min each time. Under these conditions, the extraction yields of polysaccharides, flavonoids and saponins were 3.728%, 0.135% and 1.019%, respectively. In conclusion, the optimized process is a time-saving, highly efficient, energy-saving new method to extract functional components from Radix Astragalus.
