| 摘 要： | 大戟科乌桕（Triadica sebifera）是我国南方重要的经济和绿化树种。分析了乌桕叶片乳汁中单宁和类黄酮的含量，并与叶片中单宁和类黄酮的含量进行对比。研究发现，在乳汁和叶片中共同检测到的2种单宁和2种类黄酮物质，它们在叶片中的浓度远远高于乳汁中的浓度。这表明乌桕中的单宁和类黄酮这类防御物质主要存在于叶片中。乌桕各种群间单宁与类黄酮含量都有显著差异，这可能是不同种群所处的生态环境以及面临植食昆虫的不同而导致的。

| Abstract: | Triadica sebifera （Euphorbiaceae） is an important economic and ornamental tree species in South China. Here, we analyzed and compared tannins and flavonoids content in both tallow leaves and latex. We found that the content of two tannins and two flavonoids in latex were lower than those in leaves. This indicated that most tannins and flavonoids existed in tallow leaves. We also found that tannins and flavonoids content differed among seven populations, which may be associated with different habitats and herbivores. |
