Figure 7.
Three-dimensional response surface plots for the content (µg mg−1) of insoluble phenolic compounds determined using High-performance liquid chromatography (HPLC) coupled to a tandem quadrupole mass spectrometer: Quinic acid (a), Catechin (b), 2,3, Dihydrobenzoic acid (c), Quertcetin-3-glucoside (d), Gallic acid (e), Ferulic acid (f), p-Coumaric acid (g), Luteolin-4-O-glucoside (h), and Kaempferol rutinoside (i) as a function of the interaction between germination temperature and time. The red line corresponds with the control (ungerminated seed) and the red point with the value for optimum conditions (21 °C and 3.5 days).
