| Uses | Antheraxanthin is a carotenoid pigment in the xanthophyll-cycle. Antheraxanthin levels were found to be higher in plants during depressions of photosystem II (PSII) efficiency. | | Definition | ChEBI: Antheraxanthin is an epoxycarotenol that is beta-carotene-3,3'-diol in which one of the one of the endocyclic double bonds has been oxidised to the corresponding epoxide. It is a neutral yellow plant pigment found in Euglenophyta. It has a role as a biological pigment, a plant metabolite and a marine metabolite. | | Purification Methods | Likely impurities are violaxanthin (see later) and mutatoxanthin (which contains a dihydrofuran ring derived from the epoxy group of antheraxanthin). Purify it by chromatography on columns of Ca(OH)2 and of ZnCO3. It crystallises from *C6H6/MeOH as needles or thin plates. Store it in the dark, under N2 or Ar at -20o. In CHCl3/SbCl2 it gives a blue colour with max at 587nm and gives a stable blue colour with conc HCl. [Karrer & Oswald Helv Chim Acta 18 1303 1935, Karrer & Jucker Helv Chim Acta 28 300 |
