薄层扫描法测定不同品种和产地化橘红中异欧前胡素的含量

Determination of isoimperatorin in Exocarpium citri grandis from various species and origins by TLC-Scanning

目的 :测定 1 0批不同品种和产地化橘红中异欧前胡素的含量。方法 :以薄层扫描法在 30 5nm波长处进行测定。结果 :化橘红中异欧前胡素的含量较低 ,约为十万分之几至万分之几 ,且分布并无一定的规律。结论 :化橘红中异欧前胡素的含量虽低 ,但应用本方法进行测定非常灵敏 ,方法简便 。

Objective: To determinate the content of isoimperatorin in Exocarpium citri grandis from 10 various species and origins. Methods: The isoimperatorin was determinated at 305nm by TLC Scanning. Results: The content of isoimperatorin in Exocarpium citri grandis was very low, and the law of distribution could not be found. Conclusion: Although the content of isoimperatorin in Exocarpium citri grandis was very low, the method is very sensitive and simple and the result is accurate.
