∗All carotenoids except β-carotene were quantified using UHPLC-ESI-MS on the basis of their retention times compared with authentic standards; β-carotene was detected and quantified by UHPLC. DW, dry weight. Values represent mean ± SD of triplicate analysis (n = 3) with six replicates. Different letters (a-c) denote a significant difference between mean values within the same column.
