The structure of dimethylcrocetin (DMCRT), prepared by alkaline hydrolysis in methanol of the glucosidic carotenoids extracted from the stigmata of the Crocus sativus L. flowers, has been determined. The molecule has the all-trans configuration and is planar forming a long conjugated system. The C-O bond length values of the two ester groups are shortened as expected. The compound (C 11H 14O 2) 2 crystallizes in the orthorhombic space group Pbcn with a=12.5907(7), b=7.5639(5) and c=21.963(2)Å. Dimethylcrocetin has characteristic Infrared absorptions at 1697 cm -1 θ{symbol} (C=O) and 1229 cm -1 θ{symbol} (C-O) and characteristic Raman vibrational modes at 1542 cm -1 θ{symbol} (C=C) and 1166 cm -1 θ{symbol} (C-C). © 1994 Plenum Publishing Corporation. |
