List of identified carotenoids in D. tertiolecta.

The mass-to-charge ratio, retention time (RT), reproducibility (R.S.D. RT and R.S.D. area ratio), separation factor (α), and resolution (Rs) were described.aNEO, neoxanthin; VIO, violaxanthin; ANT, anthraxanthin; LUT, lutein; γCAR, γ-carotene; αCAR, α-carotene; βCAR, β-carotene; IS*, internal standard.bData were obtained from inter-day variability testing performed by measuring the RT and area ratio of carotenoids on the three different days, with three determinations each day, for total of nine determinations.cSeparation factor (α) = (RTn+1-RT0)/(RTn-RT0), where RTn is the retention time of a compound, and RT0 is the retention time of an unretained peak.dRs = 2 (RTn+1-RTn)/(Wn+Wn+1), where Wn is the band width of a compound at the baseline.eValues in parentheses represent two neighboring peaks.
