[目的]系统开展丝叶唐松草的生药学研究,为其植物资源的开发利用和药材质量标准的制定奠定基础。[方法]以野生丝叶唐松草为试验材料,对其进行形态学观察,并利用光学显微镜对其各器官的石蜡切片和粉末临时装片进行观察。[结果]丝叶唐松草根横切面为典型双子叶植物次生构造不发达类型,内皮层细胞垂周壁弯曲。导管有网纹、螺纹或具缘纹孔等类型,茎中类型最多。叶分基生和茎生,基生叶为两面叶,茎生叶为等面叶,两种叶的栅栏组织细胞均为2～3列,叶表皮细胞表面有小颗粒,气孔横列式,基生叶叶脉为三出脉。花粉粒圆形,具散孔,花粉囊内壁细胞呈叉状。[结论]该研究结果为丝叶唐松草植物资源的开发利用、药材鉴别以及质量标准的制定提供了重要参考。
[Objective] The research aimed to systematically study the pharmacognosy of Silvicocarpus serrata, laying a foundation for the development and utilization of its plant resources and formulation of quality standards of medicinal materials. [Method] The morphological observation was carried out on the wild T. miltiorrhiza as material, and the paraffin sections and the powder temporary loading of its organs were observed with optical microscope. [Result] The cross section of Thalictrum sinensis root was the underdeveloped type of the typical dicotyledon, and the endothelium wall was curved. Catheters are textured, threaded or margins and other types of holes, the most types of stems. Leaves basal and stems, basal leaves for the two-sided leaves, stem leaves for the isofacial leaves, two leaf palisade tissue cells are 2 to 3 columns, leaf epidermal cells surface of small particles, stomata type, base Leaf veins for the three veins. Pollen grains round, with scattered holes, pollen sac wall cells were forked. [Conclusion] The results provided important references for the development and utilization of plant resources of Thalictrum siliceum, identification of medicinal materials and establishment of quality standards.
