摘要：

Carotenoid metabolites are common plant constituents with significant importance for the flavor and aroma of fruits. Three new carotenoid derivatives, (2E, 4E)-8-hydroxy-2,7-dimethyl-2,4-decadiene-1,10- dioic acid 1-O-beta-D-glucopyranosyl ester (1), (2Z, 4E)-8-beta-D-glucopyranosyloxy-2,7-dimethyl-2,4- decadiene-1,10-dioic acid ( 3), and 3,9-dihydroxymegastigmast-5-ene-3-O-[beta-D-glucopyranosyl-(1 -> 6)]-beta-D-glucopyranoside (5), as well as three known compounds, have been isolated from the ethanolic extract of peels of Cydonia vulgaris, the fruit of a shrub belonging to the same family as the apple. All the compounds were identified by spectroscopic techniques, especially 1D and 2D NMR. Antioxidant activities of all the isolated metabolites were assessed by measuring their ability to scavenge DPPH radical and superoxide radical (O2(.-)) and to induce the reduction of Mo(VI).
