摘　　要：目的：探讨用ＰＡＰＤ技术解决Ｃｕｒｃｕｍａ属植物和药物分类存在的问题和争议。方法：对温郁金Ｃ．ｗｅｎｙｕｊｉｎ和川郁金Ｃ．ｓｉｃｈｕａｎｅｎｓｉｓ进行了ＰＡＰＤ研究。结果：２种亲缘关系很近，聚类结果表明难以从ＤＮＡ水平上把二者划分为２个种。结论：结合化学和形态资料，我们认为２种应予以合并，学名应用Ｃ．ｗｅｎｙｕｊｉｎ，但温郁金和川郁金经长期栽培，化学品质有一些区别，可分为２个药材品种。同时也指出了用花葶中央出和侧生作为分类依据值得商榷。此外，还证明温郁金与毛郁金Ｃ．Objective:To discuss the problem of classifying Curcuma for Medical purposes.Method:RAPD was used to detect the DNA polymorphism within and among Curcuma wenyujin,C.sichuanensis and C.aromatica.Result:It is hard to differentiate between C.wenyujin and C.sichuanensis from the DNA level.The relationship between C.wenyujin and C.aromatica was also analyzed.Conclusion:Based on the morphological and chemical data,it is suggested that these two species should be combined into one and that classification based on peduncle central or peduncle lateral may not be right.This method will help to some degree to solve the problem of certifying the medicinal plant Curcuma.
