摘 要 ：吴茱萸作为一种重要的中药具有不同的变种，疏毛吴茱萸和石虎。AFLP技术和ITS区测序技术被用于鉴定14株吴茱萸、疏毛吴茱萸和石虎样品。ITS测序发现吴茱萸及其变种具有高度相似性，一致性达97%。在吴茱萸与其变种之间发现有一个SNP位点差异。扩增性片段长度多态性在它们之间具有差异条带。根据上述结果，分子鉴定方法能够用于鉴别吴茱萸及其变种。

Abstract:Evodia rutaecarpa(Juss.) Benth is an important medicinal plant species that has diffierent varieties, namely E.rutaecarpa(Juss.) Benth. var. officinalis(Dode) Huang, and E.rutaecarpa(Juss.) Benth. var. bodinieri(Dode) Huang. AFLP technique and ITS region sequencing were used to distinguish 14 samples belonging to the three varieties of E.rutaecarpa(Juss.) Benth. Sequence analysis of the ITS regions amplified from the three varieties of E.rutaecarpa(Juss.) Benth. indicated that ITS regions were highly similar and the identities was more than 97%. A SNP nucleotide was discovered between E.rutaecarpa(Juss.) Benth. and its two varieties. Amplified fragment length polymorphism was compared among E.rutaecarpa(Juss.) Benth, E.rutaecarpa(Juss.) Benth. var. officinalis(Dode) Huang and E.rutaecarpa(Juss.) Benth. var. bodinieri(Dode) Huang and different specific bands appeared among three varieties of E.rutaecarpa(Juss.) Benth. Based on these specific markers, molecular authentication methods can be developed to identify and distinguish E.rutaecarpa(Juss.) Benth and its two varieties.
