金铁锁野生品与栽培品的鉴别比较研究

Identificate Comparison of Wild and Cultivated Psammosilenes Radix

目的探讨栽培金铁锁代替野生金铁锁药用的可行性,为野生金铁锁的资源保护和可持续利用奠定基础。方法采用来源鉴别、性状鉴别、显微及理化鉴别的方法对栽培金铁锁与野生金铁锁进行鉴别比较研究。结果二者植物形态、性状及显微特征有很大的相似性;薄层色谱斑点数目、颜色及Rf值也基本相似。结论初步论证了人工栽培金铁锁替代野生金铁锁药用的可行性,也是对濒危植物金铁锁进行资源保护的一种可行性尝试。

Objective To investigate the feasibility of cultivated substituting for wild Psammosilenes Radix and lay foundations for resource protection and sustainable use. Methods To study its morphological characteristics of origin plant, macroscopic, microscopic and physiochemical characteristics used in pharmacognostic identification. Results There is notable similarity among plant morphogenesis, characteristic and microscopical structure. There is similarity among the number and colour of TLC spots,the value of Rf. Conclusion This study preliminary confirmed that the cultivated can be the substitutes of the wild Psammosilenes Radix, and this may be the efficient way for the conservation of the endangered resources.
