5种酸模属药用植物的形态组织学研究

摘要

OBJECTIVE:To compare and study morphology and histology of 5 Rumex species,and to provide evidence for specie identification of Rumex and the formulation of quality standard for Rumex madaio. METHODS:The original plant identifica-tion,morphological identification and microscopic identification methods were adopted to compare Rumex patientia,Rumex cris-pus,Rumex hadroocarpus,Rumex dentatus and Rumex maritimus in respects of basal leaf morphology,inner tepal,cross section of root and medical material power. RESULTS & CONCLUSIONS:There were differences among 5 Rumex species in respects of original plant morphology,root property,transverse section and powder microscopic characteristics. The edge and morphology of basal leaf and inner tepal in flower and fruit period were different greatly. Abnormal vascular bundle of transverse section could be used as identification points of Rumex species.%目的：对5种酸模属药用植物进行形态组织学比较研究，为酸模属药用植物的品种鉴别、土大黄药材质量标准的制订提供实验依据。方法：采用原植物鉴别、根性状鉴别与显微鉴别方法，比较了巴天酸模Rumex patientia L.、皱叶酸模Rumex crispus L.、锐齿酸模Rumex hadroocarpus Rech.、齿果酸模Rumex dentatus L.和长刺酸模Rumex maritimus L.等5种酸模属植物的基生叶形态、内花被片、根横切面与药材粉末的特征。结果与结论：5种酸模属植物在原植物形态、根性状、横切面、粉末显微特征方面均存在差别，其原植物基生叶、花果期内花被片边缘及形态差异较大，横切面异形维管束等可作为酸模属药材的鉴别要点。
