图1. 丁香属组系水平的次生代谢成分相对占比
色块内颜色从深到浅表示各类产物的相对数量占比从高到低的连续变化(组系内特定类别产物的相对数量占比=特定类别产物的成分计数/该组系内所有类别产物计数总和), 同一类别产物包含具有相同母核但取代基团、基团数量、基团位置和空间构象不同的化合物。热图下方的不同颜色条表示不同类别产物。为保证成分计数占比分析的客观性, 图中每个物种收入的成分信息需至少来自3篇文献。欧丁香系的阿富汗丁香及红丁香系的辽东丁香和西蜀丁香因各仅有1篇文献而暂未收入。

Figure 1. Proportion of secondary metabolites in Syringa at the level of series (section)
The color in the block progressively varying from dark to light represents the continuous change in the percentage of components in the series (section) from high to low (the percentage of specific type of components in a series (section) = the number of specific type of components in a series (section)/the total number of components in this series (section)). The products of the same type include different components with the same parent nucleus but different in substituent groups, group numbers, group positions and conformations. The different color-stipes below the heatmap represent different types of products. In order to ensure the objective counting of the components, at least three reference were required for the metabolite information of each species. Therefore, the S. afghanica in Ser. Syringa as well as the S. wolfii and S. komarowii in Ser. Villosae has not been included because only one related reference was found.
