LC-MS analysis of carotenoids from Dunaliella salina grown for nine days under high light in control stress medium. The diode array detector (DAD) profiles of carotenoid pigments monitored at 478 nm (a); extracted ion chromatograms (EIC) showing the peaks of α- and β-carotene (b) and lutein (c); mass spectrometric identification of lutein (m/z 568.4357, (d)), α-carotene (m/z 536.4435, (e)), and β-carotene (m/z 536.4446, (f)).
