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。
Tuckahoe in the medicinal cross-section of a class of white and pink-brown 2 species. In the previous experiment found that two kinds of cross-section color Smilax in the anti-inflammatory effects and chemical composition are quite different. In this paper, the total tannin content of 28 red tawny brown and white tuckahoe isolates collected from 28 different places were analyzed by UV-Vis spectrophotometry for the first time to provide some information for the rational development and utilization of quality control Experimental and theoretical basis. In the experiment, we improved the sample recovery in the method of determination of tannin content in the 2010 edition of “Chinese Pharmacopoeia”, and added the sample recovery test with tannic acid instead of gallic acid.
