目的:对鲫鱼胆进行显微鉴别研究。方法:采用石蜡切片法对鲫鱼胆根、茎、叶进行切片,采用显微技术观察组织构造及显微特征。结果:根横切面韧皮部外侧具多个纤维束间断排列成环;茎横切面表皮具非腺毛及星状毛,皮层具50~57个分泌腔呈环状排列,有草酸钙簇晶散在,皮层与韧皮部间含纤维束;叶横切面表皮多见非腺毛,下表皮细胞具草酸钙簇晶,维管束周韧型,薄壁组织中有分泌腔和草酸钙簇晶分布;叶表皮具细密脑纹状角质层纹理及非腺毛;上表皮无气孔;下表皮气孔为不等式,含草酸钙簇晶;粉末可见星状毛、非腺毛、草酸钙簇晶、厚壁细胞、导管、纤维、淀粉粒。结论:鲫鱼胆生药学特征明显,可为鲫鱼胆的鉴定与开发利用提供参考依据。
Objective: To study the microscopic identification of crucian carp. Methods: The bile root, stem and leaf of crucian carp were sliced by paraffin section method. Microstructure was observed by microscopy. Results: There were many fiber bundles arranged in a circle on the lateral phloem. The cross-section of the stems had non-glandular trichomes and stellate trichomes. The cortex had 50 ~ 57 secretion cavities arranged in a circle with scattered calcium oxalate clusters, Cortical and phloem containing fiber bundles; leaf cross-section of the surface of the common non-glandular hair, the lower epidermal cells with calcium oxalate cluster, vascular bundles week tough, parenchyma tissue secretion chamber and calcium oxalate cluster distribution; leaf epidermis Fine brain striated cuticle texture and non-glandular hairs; upper epidermis without pores; lower epidermis stomatal inequalities, containing clusters of calcium oxalate; powder visible stellate hair, non-glandular hair, calcium oxalate cluster, thick walled cells, Fiber, starch granules. Conclusion: The crude drug of Carassius auratus is obvious, which can provide reference for the identification and development of Carassius auratus.
