Description6-Epikarpoxanthin belongs to the class of organic compounds known as xanthophylls. These are carotenoids containing an oxygenated carotene backbone. Carotenes are characterized by the presence of two end-groups (mostly cyclohexene rings, but also cyclopentene rings or acyclic groups) linked by a long branched alkyl chain. Carotenes belonging form a subgroup of the carotenoids family. Xanthophylls arise by oxygenation of the carotene backbone. Thus, 6-epikarpoxanthin is considered to be an isoprenoid. (1s,2r,4s)-1-[(1e,3e,5e,7e,9e,11e,13e,15e,17e)-18-[(4r)-4-hydroxy-2,6,6-trimethylcyclohex-1-en-1-yl]-3,7,12,16-tetramethyloctadeca-1,3,5,7,9,11,13,15,17-nonaen-1-yl]-2,6,6-trimethylcyclohexane-1,2,4-triol is found in Citrus reticulata and Lilium lancifolium. Based on a literature review very few articles have been published on 6-epikarpoxanthin.
