目的对太白大黄的叶进行组织学及形态学研究,为鉴别该品种提供依据。方法观察太白大黄原植物形态性状及其叶形态、外表、断面特征等,并通过石蜡切片,观察其组织显微结构;结合TCL和荧光反应对其化学成分进行预试。结果太白大黄与大黄属其他可供药用的几种大黄(掌叶大黄R.palmatum、唐古特大黄R.tanguticum Maxim.ex Regel、药用大黄R.officinale Baill.)在植物形态、叶性状及其组织结构方面存在明显差异。结论太白大黄可能为蓼科大黄属一种新品种,且具有较高的药用价值。
OBJECTIVE To study the histology and morphology of the leaves of Taibai Rhubarb, and provide the basis for identifying the varieties. Methods Morphology, morphology, appearance and cross section of the plant were observed. The microstructure of the plant was observed by paraffin section. The chemical composition of the plant was preliminarily tested by TCL and fluorescence reaction. The results of Taibai rhubarb and other rhubarb medicinal several rhubarb (Rhubarb palm R. rutum, rhubarb R. tanguticum Maxim.ex Regel, rhubarb R.officinale Baill.) In plant morphology, leaf traits and There are obvious differences in organizational structure. Conclusion Taibai rhubarb may be a new species of Polygonaceae Rheum, and has high medicinal value.
