Figure 3
Comparison of the different conformational structures of nobiletin. The non-H atoms of NOB1 and NOB2 are shown in red and green, respectively. The H atoms in both structures are shown in white. The crystal structure obtained by the sponge method contained a pair of enantiomers of nobiletin in the crystal lattice with the space group C2/c, and one of these enantiomers is shown in the figure. |
