摘要: 对七子花不同器官的黄酮、鞣质、生物碱、皂甙、木质素、绿原酸等6种次生代谢产物的含量进行测定与分析。结果显示:6种次生代谢产物总量和各成分在七子花不同营养器官中的含量均具有一定的差异,总含量以老根最高,但主要以木质素为主;黄酮、总皂甙和总生物碱的含量以叶片最高,分别为24.13、5.51、31.08 g·kg-1;绿原酸在花中含量最高,其次是叶,分别为38.74、37.13 g·kg-1;鞣质在幼根中含量最高,为9.33 g·kg-1;木质素以老根为最高,是120.43 g·kg-1。这6种次生代谢产物在不同器官中含量与它们的合成途径、运输方向和作用部位有一定的关系。

Abstract: The contents of 6 secondary metabolites, such as flavonoid, tannin, alkaloid, saponin, lignin and chlorogenic acid, in the different organs of Heptacodium miconioides were determined and analyzed. The results showed that there were certain differences among the contents of 6 secondary metabolites in the different organs. The secondary metabolites total content in the oldest root was the highest and the major component was lignin. The content of flavonoid, sponin and alkaloid in the leaves was the highest (24.13, 5.51, 31.08 g·kg-1, respectively). The content of chlorogenic acid in flowers and leaves was higher than other organs (38.74, 37.13 g·kg-1, respectively). The content of tannin in the young root was the highest (9.33 g·kg-1). The content of lignin in the old root was the highest (120.43 g·kg-1). The contents of 6 secondary metabolites in the different organs of H. miconioides were definitely correlated with their synthesis pathway,transport direction and effect part.
