STRUCTURE OF CARTHAMIN

Abstract

Abstract The structure 6, 1-(2,6-diketo-3-glucosyl-3,4-dihydroxy-5-p-hydroxycinnamoyl)-cyclohex-4-enylidene-1′-(2′,3′,4′-trihydroxy-3′-glucosyl-5′-p-hydroxycinnamoyl-6′-keto)-cyclohexa-1′,4′-dienylmethane, was assigned for carthamin on the basis of its spectroscopic evidence and hydrolytic behavior.
