Fig. 3

Correlation matrix between antioxidant capacity assays (ABTS, DPPH, FRAP) and bioactive compounds (TPC and TFC) in leaves and fruits of P. nervosum parasitizing three different host species (Laurel—L. nobilis, Cucarda—H. rosa-sinensis, Alamo—P. alba). Correlation coefficients (r) are presented in each cell, with statistical significance indicated by asterisks (*p < 0.05; **p < 0.01; ***p < 0.001). Diagonal plots represent the density distributions of each variable, while lower triangular panels show scatterplots with fitted regression curves. The matrix illustrates host- and tissue-specific relationships between phenolic compounds and antioxidant properties.
