- ‘Concentrations of total carotenoids and total xanthophyll were greater for plants grown at low temperature.’

- ‘Retinal xanthophyll is a carotenoid, chemically related to vitamin A, whose absorption spectrum peaks at about 460 nm and ranges from 480 nm down to 390 nm.’
- ‘There is now an extensive literature based on in vivo and in vitro studies that deal with mechanistic aspects of xanthophyll pigment-dependent photoprotection.’
Mid 19th century: from Greek xanthos ‘yellow’ + phullon ‘leaf’.
