Comparison of flavonoid concentrations among color morphs. Six classes of flavonoids were identified by HPLC: (A) Cyanidin, (B) Rutin, (C) Quercetin, (D) Luteolin, (E) Apigenin, and (F) Isovitexin. Cyanidin is the primary anthocyanin pigment. The remaining five flavonoids are intermediates in the pathway (see Figure 4). Log transformed, size corrected relative peak areas are compared for white, light pink, and dark pink samples. The boxes represent the 25th and 75th percentiles, the whiskers are the 5th and 95th percentiles, the central solid lines are the median values, and circles represents outliers.
