摘　　要：目的研究马山前胡的显微特征。方法采用显微结构鉴别方法鉴别马山前胡。结果根及根茎木栓层厚,皮层有裂隙并散在油管,薄壁细胞中多含棕色物;韧皮部可见排列成环状的油管及散在的筛管群,导管细胞壁不均匀增厚,有些内含黄棕色填充物。茎中油管易见。叶的栅栏组织由3～4列圆柱形细胞组成,薄壁细胞中常含有类似橙皮苷的结晶,维管束上下方及韧皮部均有油管。根及根茎的粉末中可见众多棕色聚集物,腔内常含棕黄色填充物的网纹导管,含分泌物棕黄色油管碎片。结论以上显微特征稳定、可靠,可作为鉴别马山前胡的依据。OBJECTIVE To study the microscopic characteristics of Peucedanum mashanense.METHODS Microscopic identification method was used to study the microscopic features of Peucedanum mashanense.RESULTS In cross section of the roots and rhizomes,the cork layer was thick.The cortex showed crannies and scattered vittas and its parenchyma cells mostly contained brown substances.The phloem had vittas ranked in a ring and scattered sieve tube groups.The cell wall of the vessels,some of which comprised yellowish brown substances,was unevenly thickened.Vittas were found in the stems easily.In the leaf cross section,the palisade tissue consisted of 3-4 layers of cylindrical cells.Parenchyma cells contained crystals,which were similar with aurantiamarin.Vittas were discovered above and below the vascular bundles and in the phloem.Within the powder of the roots and rootstalks,brown substances aggregated abundantly.Reticulate vessels generally contained brownish yellow substances and vitta fragments contained brownish yellow secretion.CONCLUSION Those above features are dependable,stable and can serve as references for the identification of Peucedanum mashanense.
