Preliminary analysis of metabolomics data. Comparison of metabolite composition and content in petals. A Principal component analysis (PCA) of the metabolite quantification in petals of three colors (W_Flo, Y_Flo, P_Flo). B Cluster analysis of all metabolites from samples of W_Flo, Y_Flo and P_Flo. In the heat map, different colors represent the degree of accumulation of each metabolite, with red to blue indicating high to low. C Detailed classification of flavonoid metabolites
