摘要
土茯苓在药材断面有类白色及淡红棕色2种。在前期的实验发现,2种断面颜色的土茯苓在抗炎效果和化学成分方面有较大差异。该文首次以紫外-可见分光光度法对28个不同采集地断面红棕色及类白色土茯苓中的总鞣质含量进行比较分析,旨在为该药材资源的合理开发利用及质量控制提供一定的实验及理论依据。在实验中对2010年版《中国药典》鞣质含量测定方法中加样回收进行了改进,以鞣酸代替没食子酸进行加样回收试验。
There are two types of decoction of Smilax glabra due to its reddish brown or offwhite colored cross section. These two kinds of decoction were found that they have large difference in antiinflammatory effects and chemical constituents in the prelimina ry experiments. Comparing and analyzing the content of total tannin in these two kinds of decoction of S. glabra from 28 areas by UV Vis spectrophotometry were first used to provide some experimental and theoretical development and utilization of this medicinal re source and quality control. Also, the sample recovery test required in Chinese Pharmacopoeia was improved by adding tannic acid in stead of gallic acid to samples.
