Tóth}, title = {Confirmation of the absolute (3R,3 S,6 R)-configuration of (all-E)-3 -epilutein}, abstract = {Circular dichroism (CD) spectroscopy was used to distinguish between the isomeric (all-E)-configured 3 -epilutein (2) and 6 -epilutein (8) to establish the absolute configuration of epilutein samples of different (natural and semisynthetic) origin, including samples of 2 obtained from thermally processed sorrel. Thus, the CD data of lutein (1) and epilutein samples (2) were compared. Our results unambiguously confirmed the (3R,3 S,6 R)- configuration of all epilutein samples. Compound 2 was thoroughly characterized, and its 13C-NMR data are published herewith for the first time.}, year = {2004}, journal = {Helvetica Chimica Acta}, volume = {87}, pages = {2159-2168}, month = {2004}, url = {http://www.scopus.com/inward/record.url?eid=2-s2.0-4644309094&partnerID=40&md5=434657a85824e8587c4d5c66ba0051a5}, note = {Cited By :11Export Date: 25 February 2016}, }
