In this paper, the structure characters of steroidal alkaloids from Buxaceae were discussed. Using the steroidal alkaloids for the chemotaxonomic characters, the evidences of chemotaxonomy and plant systematics of Buxaceae were studied. The interrelations among three genera, Buxus, Pachysandra, and Sarcococca were discussed.

本文讨论了黄杨科植物甾体生物碱成分的结构特征；以甾体生物碱作为化学分类学的特征物质，初步探讨了黄杨科植物化学分类学的依据和系统位置；同时讨论了黄杨属、板凳果属（Pachysandra，又称富贵草属）和野扇花属3属间的相互关系。

In order to identify plants better, the identification of the plants is more and more important, along with it, plants taxonomy is brought, the taxonomy of plants researches classification of all plant species, the relative between different species and the nature system of vegetable kingdom.

为了能更好的运用植物与识别植物，对植物的分类与识别，越来越体现出其重要性。因此产生了植物分类学的说法，植物分类学是研究植物类群的分类、探索植物间的亲缘关系和阐明植物界自然系统得科学。

The fields overlap however in the science of phylogenetic systematics – colloquially often called "cladism" or "cladistics"–, where only phylogenetic trees are used to delimit taxa, which represent groups of lineage-connected individuals.

系统发生学与分类学的交互重叠区域是系统发生分类学，常俗称为&分支学说&或&遗传分类学&；在系统发生分类学中，只用系统发生树来定分类的界限，这些分类代表血统相关个体组成的群。

In morphology, cladistic and numerical taxonomy are used respectivelyto analyze six species of Montifringilla and to construct the phylogenetic trees,and to discuss the relationship and taxonomic status of Montifringilla spp.
