水蓼的性状及显微鉴定研究

Macroscopic and Microscopic Identifications of Polygonum Hydropiper L.

目的:建立水蓼的生药学鉴定方法,为该药材的深入研究提供参考依据。方法:采用性状鉴别、组织及粉末显微鉴别方法对水蓼药材进行鉴定分析。结果:水蓼茎横切面可见皮层狭窄,维管束20~30个,断续排列成环,髓部宽广。叶表面片可见腺毛与非腺毛,气孔多为平轴式,偶见不等式或不定式。粉末中草酸钙簇晶众多,排列成行或散在;导管多为螺纹;花粉粒类球形,表面具网状雕纹,偶见石细胞。结论:研究结果可为水蓼的药材鉴定、质量标准及资源利用提供科学依据。

Objective To establish pharmacognosy identification method of Polygonum hydropiper L.and provide references for the further research of this plant. Methods Morphology, tissue and powder characteristics of P. hydropiper were observed and analyzed. Results From the transverse section of stem, thin cortex, wide pith and 20-30 vascular bundles intermittently arranged into a ring could be seen. From the surface sheet of leaves, glandular and non-glandular hairs could be observed. Most of the stoma are paracytic type, anisocytic and anomocytic type can be found occasionally. In the powders, numerous calcium oxalate clusters arranged in rows of scattered and spiral vessels could be found. Pollen grains were spherical and reticulated, stone cells could be observed occasionally. Conclusion The results of this study could provide scientific references for authentification, quality standardization and resource utilization of P. hydropiper.
