不同采样点息半夏质量对比研究

Study on quality of Pinellia ternate(Thunb.)Breit of Xixian county from different sampling points

分别从性状鉴别、粉末显微鉴别、薄层色谱鉴别、水分、总灰分、浸出物检查、总酸含量测定等方面,比较了7个采样点息半夏(Pinellia ternate(Thunb.)Breit of Xixian county)的质量。结果表明,7个采样点息半夏粉末显微特征、薄层色谱一致;但性状、水分、总灰分、浸出物和总酸含量有差异。其种源、繁育方式、野生环境、培育条件对息半夏质量有影响。

From the characteristics,powder microscopy,TLC,water content,total ash,extract examination and total acid content,the quality differences of Pinellia ternate(Thunb.)Breit of Xixian county from 7 sampling points were compared.Results showed that Pinellia ternate(Thunb.)Breit powder of Xixian county from 7 sampling points have the same microscopic characteristics and the results of TLC,but their characters,water content,total ash content,extracts and total acid content are different.Provenance,breeding method,wild environment and rearing condition have influence on the quality.
