【摘要】 测定不同产地龙胆多糖的含量,为龙胆的质量评价提供理论依据。利用超声波提取技术,采用苯酚-浓硫酸法、紫外-可见分光光度法测定左家等10个不同产地龙胆的多糖含量。各不同产地龙胆多糖含量分别为:王岗15.4834%,鸡西4.6988%,绥化4.7662%,左家6.3750%,新宾10.3737%,桓仁8.7152%,本溪6.1526%,安国8.6772%,侯马10.0964%,桃花潭24.8747%。结论:不同产地龙胆多糖的含量差异很大,其中以安徽省桃花潭地区龙胆多糖的含量最多,而黑龙江省鸡西地区的最少。更多还原

【Abstract】 To study the contents of polysaccharides in Gentiana from 10 different areas,and to provide the basis of theory for the quantity evaluation of Gentiana.Methods:To determine the contents of polysaccharides in Gentiana from 10 different areas using the wave by the phenolsulfuric acid method.Results:The contents of polysaccharides in Gentiana from 10 different areas are: Wang Gan 15.4834%,Ji Xi 4.6988%,Sui Hua 4.7662%,Zuo Jia 6.3750%,Xin Bin 10.3737%,Huan Ren 8.7152%,Ben Xi 6.1526%,An Guo 8.6772%,Hou Ma 10.0964%,Tao Hua-tan 24.8747%.Conclusion:The contents are obvious of polysaccharides in Gentiana collected in different areas.Tao Hua-tan in An Hui province is the area which has the highest content of Gentianae polysaccharides,and Ji Xi in Hei Long-jiang province has the lowest content.更多还原
