山西中部7种地衣的解剖结构及化学性质

摘要

对采自山西中部7种地衣标本，从形态学、解剖学及化学方面进行综合观察研究，利用薄层层析法（TCL）对地衣的化学成分进行检测，并根据观察及检测结果对地衣进行了聚类分析。结果表明：7种地衣的基本结构具有相似性，均为异层型地衣，由上皮层、藻层、髓层及下皮层构成，不同属种地衣的繁殖器官类型及附属结构有所差异；检测出含有化学成分4种；并通过聚类对其亲缘关系进行探讨。%With seven species of lichens in central Shanxi province, the detection was conducted to study the morphology, anato-my and chemistry, employ thin layer chromatography ( TLC) to analyze chemical constituents to analyze similar traits.The lichen structures of seven species are similar, composed of the upper cortex, the algal layer, the medulla and the next cor-tex, while different species of lichen propagative organs and accessory structures are different.Four kinds of chemical con-stituents were tested.The genetic relationship was discussed with cluster analysis.
