阜南产半夏的质量研究

目的对阜南产半夏的质量进行研究。方法分别测定4个产地半夏中游离、水解氨基酸和麻黄碱,采用高效液相色谱法对4个产地半夏的甲醇和酸性乙醇提取物的成分进行比较,用薄层色谱法对4个产地半夏的石油醚提取物的成分进行比较。结果阜南产半夏所含氨基酸总量和种类以及麻黄碱与其他产地半夏基本一致,甲醇提取物和石油醚提取物的主要成分与其他产地半夏一致,酸性乙醇提取物的一些微量成分与其他产地半夏有所差异。结论阜南产半夏品质与其他3个产地的半夏基本相同。

Quality of Pinellia ternata grown in Funan

Objective To study the quality of Pinellia ternata grown in Funan. Methods The contents of free and hydrolyzed amino acids and ephedrine in the samples from four habitats were determined. The components of methanol and acidic ethanol extracts of the four samples were compared by HPLC. The components of petroleum ether extracts of the four samples were compared by TLC. Results The content of amino acids and ephedrine and the kinds of amino acids of P. ternata grown in Funan were almost the same as those from the other three, the main components of methanol and petroleum ether extracts of P. ternata grown in Funan were the same as those from other three. Some components of acidic ethanol extracts of the four samples were different. Conclusion The quality of P. ternata grown in Funan is as good as that of the other three.
