摘　　要：探讨了几种木麻黄单宁含量与种类、年龄、部位、生态环境的关系。结果表明:8种木麻黄小枝总多酚含量排序为:细枝木麻黄(Casuarina cunninghamina)>山地木麻黄(C.junghuhniana)>山神木麻黄(C.collia)>短枝木麻黄(C.equisetifolia)>鸡冠木麻黄(C.cristata)>粗枝木麻黄(C.glauca)>肥木木麻黄(C.obesa)>滨海木麻黄(Allocasuari-na littoralis);不同年龄木麻黄小枝总多酚含量随着年龄的增加而增大。短枝木麻黄和细枝木麻黄总多酚、可溶性单宁、蛋白质结合缩合单宁以及纤维素结合缩合单宁含量大体上以细根>树皮>小枝。随着离海岸带距离的增加,木麻黄小枝总多酚含量降低。木麻黄小枝蛋白质结合态缩合单宁含量非常低,而纤维素结合态缩合单宁含量较高,这可能与木麻黄鳞片叶退化为小枝,纤维素含量高有关。Tannin contents of different Casuarina species and tannin distribution rules of species, ages, position and ecological environment were studied. The results showed that the total phenol of branchlet of Casuarina was under the order as follows ： Casuarina cunninghamina 〉 C. junghuhniana 〉 C. collia 〉 C. equisetifolia 〉 C. cristata 〉 C. glauca 〉 C. obesa 〉 Allocasuarina littoralis. The total phenol contents of branchlets of different years old of Casuarina increased with ages. The total phenol, solubility tannins, protein binding condensing tannins, fibrin binding condensing tannins contents of short and thin Casuarina branehlets were under the following order wholly ：thin root 〉 bark 〉 branchlet. With the increasing of the distance from coastal belt, the total phenol of branchlet declined. The protein binding condensing tannin of Casuarina branchlet was very low, whereas fibrin binding condenseing tannins content was highest. The mason could be the high fibrin content after Casuarina scale leaf degenerated to branchlet.
