Abstract:
Objective::Histomorphological study of the Nandinae Radix, Nandinae Caulis, Nandinae Folium, Nandinae Fructus were conducted to provide the basis for the identification of its authenticity and falsehood. Method::The origin and macroscopic identification were used to describe the plant morphology and the appearance characteristics of all medicinal parts. The microscopic characteristics of the medicinal parts, such as roots, stems, leaves, flowers, fruits, were observed and photographed by paraffin section and powder preparation techniques. Result::It was found that the morphological characteristics of the original plant were consistent with the descriptions in herbaceous books. There was no pith on the cross-section of roots. In the transverse section of stems, there were intermittent circular fiber bundles in the cortex and a cap-shaped fibrous bundle in the inner part of the xylem. In the transverse section of the leaves, the palisade tissue was wider and the fiber bundles around the main vascular bundles formed a ring. In the transverse section of petiole, the fiber bundles were arranged intermittently into rings. In the transverse section of fruit, multi-layered sclereids formed a ring in the mesocarp. The powder characteristics of root and stem mainly contained crystalliferous sclereids. There were crystal sheath fibers and stomatal infinitive in the leaf powder, and pollen grains in the flower powder, with 3-hole grooves, obvious reticulate engraving pattern in the outer wall and more reticulate cells. There were a large number of branched sclereids and calcium oxalate square crystals in the fruit powder. Conclusion::The above-mentioned morphological and microscopic features have identification significance, and provide scientific basis for the authenticity identification, the quality standard and the utilization of resources of Nandina domestica.
