摘要
目的鉴别当归藤。方法采用显微方法鉴别当归藤。结果显微特征观察中可见药材根部木栓细胞壁增厚且有些可见明显孔沟,皮层细胞内含棕色物,中柱鞘纤维、石细胞断续呈环状排列,木质部宽广;茎的韧皮部及髓部中可见离生式分泌腔散在;粉末中可见众多石细胞、棕色块、分泌腔碎片、立体结构明显的方晶。结论当归藤的显微特征明显、稳定,可作为其鉴别依据。
OBJECTIVE To identify Embelia parviflora Wall..METHODS Microscopic identification methods were used to study the microscopic structure of the plant.RESULTS In the root,phellem cells possessed thickened wall,some of which showed clear furrows.The cortical cells contained brown contents.Fibers and stone cells which ranked in a ring were obvious in the pericycle,and the xylem was broad.The phloem and pith of stem also had schizogenous secretory cavities scattered.In the powder,numerous stone cells,brown contents,fragments of secretory cavities and prisms of calcium oxalate with distinct spatial structure were observed.CONCLUSION The characteristics obtained in this study are clear,stable and can be used to identify Embelia parviflora Wall..
