厚朴七的生药鉴别

目的:对厚朴七进行生药学鉴定研究。方法:利用性状、显微与理化鉴定法对该药材进行鉴定研究,确立鉴别特征。结果:其主要特征为根茎上端有鳞毛,切面有许多白色闪光小点;根茎横切面中维管束大小相间排列成断续的环状,髓部的外侧有小型异型维管束散在,根木质部四原型;根茎及根薄壁细胞中含有淀粉粒和草酸钙针晶;粉末中淀粉粒极多,草酸钙针晶成束或散在,棕色细胞单个散在或数个相连。结论:上述特征可作为厚朴七药材的鉴别依据。

Pharmacognostic Identification of Rodersia aesculifolia

Objective: To establish pharmacognostical methods of Rodersia aesculifolia.Methods: Macroscopical,microscopic and physicochemical identification were used to authenticate this crude drug,and the identification characteristics were studied.Results: There were some palea on the rhizoma superior extremity and some white flare dot on transverse section.Vascular bundle formed into interval circularity in rhizoma transverse section,and some small atypia bundle appeared in lateral of core.Xylem of root was tetrarch.A lot of starch grain and acicular cyrstal were observed in parenchyma cell.Brown cell was present as single or several linked.Conclusion: These characteristics can be used as identification basis for Rodersia aesulifolia Batal..
