星果草属药用植物的生药鉴别研究

Pharmacognostic Identification of Medicinal Asteropyrum Plants in China

目的 :对星果草属药用植物进行系统的生药鉴别研究 ,为该类药材质量控制提供依据。方法 :野外采集 ,市场调查 ,结合文献查阅 ,形态和组织学比较研究。结果 :对药材的性状 ,根、根茎、叶的显微特征进行了描述 ,绘图。结论 :本属植物根茎的组织特征和近缘的黄连属相似 ,但有明显不同 ,属内 2种在组织上能够有效区别。为本属生药的质量控制提供了形态组织学上的依据。

Objective: To offer evidences for quality control of medicinal Asteropyrum plants. Method: Pharmacognostic studies were made through field collection, market investigation, document utilization, comparative morphology and histology. Result: The shape and properties, microscopic characteristics in root, rhizome, leaves were worked out. Conclusion: Asteropyrum can be distinguished from close relative Coptis plants by microscopic and histology characteristics. Two species in Asteropyrum can also be identified by microscopic and histology characteristics ,and the morphological and histology characteristics can be used as evidences for quality control of medicinal Asteropyrum plants.
