【摘要】 以龙胆为原料,采用正交设计的方法,以匀浆时间、匀浆次数、料液比为考察因素,对匀浆法提取龙胆中龙胆多糖工艺进行研究,确定其最佳工艺条件,为龙胆药用资源研究与开发提供可靠依据。结果表明:龙胆多糖提取最佳工艺参数为:匀浆时间9min、匀浆次数3次、料液比1︰30(g︰mL),在最佳条件下,龙胆多糖得率为12.59%。匀浆提取法操作简单、减少粉尘污染、提取率高、提取时间短,是一种高效提取龙胆多糖的方法。更多还原

【Abstract】 The method of homogenate extraction technology of Gentiana scabra Bunge polysaccharides in Gentiana scabra Bunge was researched.To determine the best technical conditions and provides the evidence and reference for Gentiana scabra Bunge polysaccharides extraction from the medicinal material or preparation.The most important influence of homogenate extraction time,extraction times,the ratio of sample to solution were set as index for orthogonal test,so as to acquire the proper extraction technical conditions of Gentiana scabra Bunge polysaccharides.The results showed the optimum condition of extraction of parameters were homogenate extracting duration for 9 min with extracted 3 times at a ratio of solid-iquid of 1∶30(g∶mL).By using the optimized parameters,the extraction yield of Gentiana scabra Bunge polysaccharides was 12.59%.It may shorten the extraction time and high yield,which was an efficient method for extracting polysaccharides.It could be used for large scale industrialized production and provides the evidence and reference for Gentiana scabra Bunge polysaccharides extraction from the medicinal material or preparation.更多还原
