Carotenoids and
phenolics compounds were validated in composite leaf samples of tested genotypes with RP-HPLC
analysis. Antioxidant activity of methanol extracts ranged from 72.0 to 85.7% which showed significantly positive correlation with anthocyanin (r = 0.75; p < 0.05), total phenol (r = 0.53; p < 0.05), flavonoids
(r = 0.56, p < 0.05), and tannin (r = 0.42; p < 0.05)
