文档介绍:专业资料参考首选不同地区桔梗多糖含量的比较张小斌(商洛学院生物医药工程系、中国中医研究院商洛中药材 GAP 科研工程中心陕西商洛 726000 ) 摘要选取陕西商洛、安徽太和和吉林延边产桔梗,采用水提取法提取桔梗粗多糖, 分别测定粗多糖含量,采用三氯乙酸-正丁醇法脱蛋白脱去多糖中粗蛋白,测定精制多糖含量,比较三个地区桔梗粗多糖及精制多糖含量。结果显示,安徽太和粗多糖含量最高,为 % ,其次为吉林延边桔梗,为 % ,陕西商洛桔梗为 % 。提取粗多糖经精制后,安徽太和、陕西商洛、吉林延边桔梗粗多糖蛋白去除率分别为: % , % 和 % ,差异不显著。精制多糖含量分别为: % , % 和 % 。结果表明安徽太和桔梗多糖含量最高,陕西商洛次之,最后为吉林延边桔梗。关键词: 桔梗;粗多糖;精制多糖;含量中图分类号: 文献标识码: 文章编号: Comparison the content of haride of platycodon in three areas Abstract: Select the platycodon ,in shangluo, anhui tai and jilin in yanbian with water to extrac the crude haride of platycodon , ahd then crude haride is determined, Use the acid-n-buoh the different method to take off the protein in the haride crude, and then to determin e the refined haride, compare the thick harides and refined haride of platycodon in these three area s. The result is showed that the highest content of haride in anhui tai, thick for %, followed by jilin yanbian balloon flower %, the minimum is shangluo balloonflower, for %. . After the e xtraction of refine d haride from crude haride ,the balloonflower thick glycoprotein removal rate in anhui tai, shangluo, jilin yanbian is more than respectively %,% and % , the difference is not significant . R efined haride is % , % and % , the results show that the contents of haride in anhui tai balloonflower highest, in shangluo is the second smallest, and finally for jilin yanbian lisianthus.
