目的:为了比较不同气候区银杏叶中黄酮和萜内酯的含量,并进一步探讨影响二者含量的环境因素。方法:采用RP-HPLC法对样品中黄酮和萜内酯进行定量分析。结果:不同气候区之间银杏叶中两类成分的含量存在很大差异,贵州高原区银杏叶中总黄酮和总内酯的含量明显高于其它地区。结论:通过系统比较全国不同银杏分布区银杏叶中有效成分的含量,为提高银杏叶质量,优化银杏叶资源提供了理论依据。

[Abstract]
To compare the contents of flavonoids and terpenlact ones in the leaves of Ginkgo biloba L. from different regions a nd di scuss the influential factors of climatic environment. RP-HPLC was used to det e rmine the flavonoids and terpenlactones. The contents of these active constitue n ts varied greatly from place to place. The contents of total flavonoids and ter p enlactones were much higher in the leaves of G. biloba. from G uizhou Plateau than those from other regions. Data from this experiment may provide a basis for the optimization of the quality and resources of G. biloba.
