The methanolic extract of saffron was separated with the aid of multilayer coil countercurrent chromatog. After purification by HPLC, the following seven novel carotenoid metabolites were identified on the basis of their spectral (UV, FTIR, MS, NMR, CD) data: (4R)-4-hydroxy-2,6,6-trimethylcyclohex-1-enecarbaldehyde O-β-D-gentiobioside (1), (4R)-4-hydroxy-2,6,6-trimethylcyclohex-1-enecarboxylic acid O-β-D-glucopyranoside (2), 6-hydroxy-3-(hydroxymethyl)-2,4,4-trimethylcyclohexa-2,5-dienone 6-O-β-D-glucopyranoside (3), (2Z)-3-methylpent-2-enedioic acid 1-[1-(2,4,4-trimethyl-3,6-dioxocyclohexenyloxy)-O-β-D-glucopyranosid-6-yl] ester (4), (5S)-5-hydroxy-7,7-dimethyl-4,5,6,7-tetrahydro-3H-isobenzofuran-1-one O-β-D-glucopyranoside (5), (1R,5S,6R)-5-(hydroxymethyl)-4,4,6-trimethyl-7-oxabicyclo[4.1.0]heptan-2-one O-β-D-glucopyranoside (6), and (1R)- 3,5,5-trimethylcyclohex-3-enol O-β-D-glucopyranoside (7).
