Notes:

Values are means of duplicate samples, each analyzed in triplicates (n = 6) ± standard deviation. Means with different superscripts within the same column are significantly different at p < 0.05. TPC, total phenolic content; TFC, total flavonoid content; TCC, total carotenoid content; LYC, lycopene content
