摘　　要：目的:研究当归藤的药材性状和显微鉴别特征。方法:分别对药材的根、茎和叶进行性状和显微鉴定。结果:经实验证实,当归藤有显著的显微特征,如:根的皮层有单个石细胞散在,在中柱部位有较多石细胞群及纤维束散在,并断续成环。茎的韧皮部宽广,在靠近形成层部位有大型的分泌细胞散在,在射线部位有石细胞群。药材粉末见晶体石细胞,石细胞有厚壁与薄壁两种。结论:上述特征可作为当归藤显微鉴别的重要参考依据。Objective： To study the morphological character and microscopic identification of Embelia parviflora.Methods： Researches on the morphological character and microscopic identification of roots and stems of Embelia parviflora were carried on respectively.Results： Significant microscopic characteristics of Embelia parviflora were confirmed.Such as single stone cells scattered in the root cortical,lots of stone cell groups and fiber bundles scattered in the column parts and became ring intermittently.Stem phloem was broad,large scale secretory cells scattered near cambium region and stone cell groups in ray parts.Crystal stone cells of thick and thin could be seen in powder.Conclusion： These features can be used as the reference for quality standard of Embelia parviflora.
