Quantification of carotenoids (µg.mg⁻¹ of extract) in MeOH/DCM dried extracts of microalgae cultivated at two light intensities, 250 µmol·m⁻²·s⁻¹ (LL) and 600 µmol·m⁻²·s⁻¹ (HL). Lut, lutein; t-Neo, t-neoxanthin; Siph, siphonaxanthin; Zea, zeaxanthin; β-Car, β-carotene; Fuco, fucoxanthin; cis-Fuco, cis-fucoxanthin; and Dt, diatoxanthin.
