Figure 3.

Bi-plot derived from a principal component analysis (PCA) showing the selectivity of the extraction solvent. Plants exposed to high light were pooled and extracted using the indicated solvents. Colored squares correspond to the observations (n = 4 for each solvent) and black triangles represent the variables. PC1 and PC2 are first and second principal components, respectively, with their percentage of explained variance. The identified prenyllipids are indicated (confront with Table 1).
