萝藦科植物分类学研究进展

Advances in taxonomic study of Asclepiadaceae

萝藦科(Asclepiadaceae)系热带植物区系的主要科,该科植物是我国重要的药用植物种质资源,在常用中药和民族民间用药中应用广泛。无论是在植物学还是中药学领域,萝藦科植物都是值得关注的重要类群。长期以来,萝藦科和夹竹桃科(Apocynaceae)以及科下多个亚科和属之间分类界定存在争议。对萝藦科的分类历史,及其在细胞学、微形态、植物化学、分子生物学等方面的研究进行系统梳理,并对其中存在的问题及存疑类群进行阐述,以期为该科植物更深入的系统分类和开发利用研究提供思路。

Asclepiadaceae is a main family in the tropical flora,and it is also a most important resouce of Chinene medicinal plants,which is widely used in traditional Chinese medicine and traditional ethno-medicine. An accurate identification of plant species is the precondition of accurate identification and pharmacological efficiency of herbs.However,the classification and definition of subfamilies and genera betweeen Asclepiadaceae and Apocynaceae have been in dispute for a long time. In this paper,taxonomy history and researches for this family in cytology,micromorphology,phytochemistry and molecular biology are systematically reviewed,the main taxonomic problems as well as taxa in dispute are elaborated,in hope to provide reference for researches in further systematic classification and exploitation of this plant taxon.
