棘茎楤木的资源学和生药学研究

Resource and pharmacognostical study on Aralia echinocaulis

目的 :开展棘茎木的资源和鉴定研究 ,为其开发提供基础资料。方法 :资源调查和鉴定。结果 :初步查明棘茎木的县级分布和生态环境 ,发现其主要分布长江流域及以南山区 ,多在民间应用 ;提出性状、显微和理化鉴定特征。结论 :棘茎木的原植物、药材形态和显微、理化特征具有鉴定价值 ;此外 ,该种有较高的开发利用价值 ,但资源难以支持持续利用 ,人工繁殖非常重要。

Objective: To provide fundamental information for its exploiting. Aralia echinocaulis by the resource and identification study on. Method: Resource survey and various identification were carried out. Result: The county level distribution and ecological environment of A. echinocaulis were initially observed. It mainly distributed in the mountainous areas of the Yangtze River basin and the south,and was usually used as folk drug. This study also displayed its morphological,microscopic and chemophysical identification features. Conclusion: The morphological features of original plant and crude drug, and the anatomical and chemophysical characteristics of A. echinocaulis are of identification value,and the species are also of greater development and utilization potentiality,but the resource does not support the sustainable utilization. Therefore,artificial propagation is apparently crucial to its exploitation.
