目的:对细叶小檗的组织构造与显微特征进行观察,为其资源的进一步开发利用以及品质评价提供科学依据。方法:(1)采用石蜡切片法制备细叶小檗根、根茎、茎和叶的组织切片,观察其组织构造及特征。(2)采用水合氯醛透化或醋酸甘油不透化制备粉末片,观察粉末的显微特征。结果:(1)细叶小檗根横切片皮层有石细胞散在,单个或成群,韧皮部中部可见韧皮纤维。(2)根茎横切片的木栓层有少量石细胞,皮层及韧皮部石细胞群伴有纤维,断续排列成环。(3)茎横切片在皮层外部有石细胞环带。(4)叶横切片上表面有栅栏细胞,通过主脉。结论:细叶小檗根、根茎、茎和叶的组织构造和粉末的显微特征比较明显,可为该药材的生药学研究和质量控制提供参考或依据。
OBJECTIVE: To observe the microstructure and microstructure of Berberis lobata, and provide a scientific basis for the further development and utilization of its resources and quality evaluation. Methods: (1) The tissue sections of roots, rhizomes, stems and leaves of Bemisia microphylla were prepared by paraffin section method and their structures and characteristics were observed. (2) using chloral hydrate or glycerin glycerol impermeable powder preparation, observe the microscopic characteristics of the powder. Results: (1) There were scattered stone cells in the transverse section of the root of barberry. Individual or group, bast fibers were observed in the middle part of the phloem. (2) rhizome cross-section of the cork layer has a small amount of stone cells, cortical and phloem cell group with fibers, intermittently arranged in a ring. (3) Stem cross-section of the cortex in the outer cortical zone. (4) Leaf cross-section of the top surface of palisade cells, through the main vein. CONCLUSION: The microstructure of roots, rhizomes, stems and leaves and the microscopic characteristics of the powder are more obvious, which may provide a reference or basis for the crude drug research and quality control.
