买麻藤科植物研究进展

买麻藤科植物是裸子植物中唯一的藤本植物,具有重要的理论研究和应用开发价值.全世界仅1属约40种,中国发现9种,分布于亚洲、非洲和南美洲的热带和亚热带地区；在理论研究方面,该科系统进化位置特殊,形态结构、化学成分和分子水平上的研究存在很大争议,仍没有解决其在裸子植物与被子植物间所处的进化位置；在应用研究方面,该科既是传统中药又富含芪类、生物碱和黄酮等活性成分,而且果实和叶片可食用；然而,在引种、驯化及培育方面研究薄弱,阻碍了该科资源的开发和利用.本文从资源分布、理论与应用研究以及开发利用等方面综述了买麻藤科植物研究进展,将为今后国内深入开展该科植物的相关研究奠定基础.

Progress on Study of Gnetaceae Plants in World

Gnetaceae, as a sole lianas (rare shrubs or arbors) in gymnosperms, plays an important roles in the studies of theoretics and applications. There is only one genus, and about 40 species in the world and 9 species in China, which distributed in the tropical and subtropical areas of Asia, Africa and South America. On the aspects of theoretical research, it is still disputed for the evolution between gymnosperms and angiosperms although a large amounts of studies have been carried out on the morphology and anatomy, chemical constituents and molecular biology. On the aspects of applicable research, the constituents of biological activities, stilbene or its derivatives, alkaloid and flavone, et al., are greatly abundant in this family. Moreover, some species have been Chinese traditional medicines in history. However, exploiture and utilization have been blocked due to its weakness on the studies of introduction, domestication and cultivation. Consequently, this article reviews that the progress on its distribution of species, the research values of theoretical and applicable research, exploiture and utilization, which will provide an basis for the further study of Gnetaceae in future.
