摘　　要：选取木兰科木兰属15种植物的108种萜类化合物成分作为研究资料,根据各种萜类化合物成分的结构类型从中找出34条可能的生源合成途径,并将各种生源途径作为数量性状,用聚类分析的方法得到木兰属各分类群之间的相关系数、作出树形分支图,根据所含萜类比较复杂成分的比例对该属的演化关系作出推论,结果表明木兰亚属与玉兰亚属是属于平行演化的两支。In this paper, the author uses 108 kinds of terpenoid components from 15 species of Magnoloia as researching data, and finds out 34 kinds of terpenoid biosynthesis pathways in Magnoloia. The author has obtained the coefficient of correlation, drawn rescaled disdance cluster combine and deduced the evolvement of genus Magnoloia, with the method of cluster analysis. Based on the analysis of the more complex structures of Sbugen. Cymbostemon and Sbugen. Magnoloia,the author points out that the evolution of Sbugen. Magnoloia and Sbugen. Cymbostemon are parallelled.
