Carotinoide der Commelinacee Palisota barteri — ein neues β-Citraurin-Vorkommen

Abstract

The deep red colour of the fruits of Palisota barteri results from a high content of Carotenoids. The main pigment now has been identified as β-Citraurin. It is esterified with the saturated fatty acids from C4, C6 ... up to C18. The main fatty acid is lauric acid. Minor pigments are Zeaxanthin and Cryptoxanthin, both esterified in the same manner as β-Citraurin, and β-Apo-8′-carotinal, β- and ξ-Carotin and a very small amount of Lycopin.
