图 3 次级代谢产物相对含量的正交偏最小二乘回归及判别分析(a, b, d, e中红点为化学分类标志物), 箱线图显示南洋杉科和柏科树脂(c)以及豆科树脂(f)化学分类标记的相对含量对比

Figure 3. Orthogonal partial least-squares regression and discriminant analysis of the relative contents of secondary metabolites (a and d); S-plot where points with different colors represent the chemotaxonomic markers, the farther away points the center, the higher contribution of the markers to the separation of the groups (b and e); Boxplots showing relative content levels of chemotaxonomic markers in group Araucariacae and Pinaceae resins and group Hymenaea resins (c and f)
