Add time:08/11/2019 Source:sciencedirect.com
A new cis isomer in the violaxanthin series has been isolated from the blossoms of Viola tricolor and identified by MS, IR and UV as the central-monocis form. It was converted to all-trans-violaxanthin by stereomutation. The CD correlation between 15-cis-violaxanthin and natural violaxanthin (5,6,5′,6′-diepoxy-5,6,5′,6′-tetrahydro- β,β-caroten-3,3′-diol) provided the basis for assignment of the absolute configurations 3S, 5R, 6S, 3′S, 5′R, 6′S. Trans—cis isomerization of all-trans-violaxanthin also resulted in 15- cis-violaxanthin. In addition a quantitative determination of the carotenoids was conducted.
