The varying concentrations of flavones apigenin and luteolin and the glycosylated derivatives vitexin, vicenin-2, and vicenin-3 and luteoside in developing seedlings of the sorghum cultivar NS5511 at 7, 11, 14, 18, 22, 25, and 29 days post-germination, as determined by UHPLC-3Q-MS/MS using optimized MRM conditions. All concentrations (y-axis, ng/g fresh weight) are mean concentration values with n = 9, and error bars indicate the standard error. Isovitexin and apigetrin were below the limit of detection. An asterisk (*) indicates the statistical significance (ANOVA followed by Tukey post hoc test at a p-value < 0.05 when comparing mean values to that of day 7).
