Concentrations of carotenoid stock solutions used to build calibration curves.

Carotenoid	Solvent		Stock carotenoid concentration (μg/mL)
cis-Neoxanthin	EtOH	2,380	19.64 ^a
Violaxanthin	EtOH	2,550	16.26 ^a
Antheraxanthin	EtOH	2,350	17.53 ^a
Astaxanthin	EtOH	2,100	1.55 ^a and 4.96 ^b
Astaxanthin	Injection solvent	-	5.12 ^b
Zeaxanthin	Acetone	2,340	32.31 ^a
Lutein	EtOH	2,550	21.57 ^a
Canthaxanthin	Hexane	2,200	0.27 ^a and 4.53 ^b
Canthaxanthin	Injection solvent	-	5.70 ^b
β-Cryptoxanthin	Hexane	2,400	35.00 ^a
β-Carotene	Hexane	2,590	24.85 ^a
Lycopene	Hexane	3,450	8.26 ^a
cis-Phytoene	Hexane	915	16.16 ^a

^a Concentration was determined spectrophotometrically; ^b Concentration was determined by dividing the mass of the carotenoid by the total volume of solution.
