Abstract: In this paper, the 13C NMR spectroscopy of flavonoid-O-glycosides was summarized which overlaps solvent system, number and identification of monosacchride, interglycosidic linkage, sugar sequence, identification of flavonoid agly cone, site glycosylation and appearance of acyl subtituents.In addition, more than fifty reference data of di-and oliga-saccharide moieties founded in flavonoid-O-glycosides were presented.

Key words: Flavonoid-O-gly coside, 13C NMR spectroscopy
