Quercetin glycosylation

Glycosylation of a flavonoid hydroxy group shifts the phenolic carbon resonance 1-2 ppm upheld and the ort/to-related carbon resonance up to almost 10 ppm (e.g. quercetin) downheld. [Pg.451]

Flavonols that accumulate in plant tissues are almost always in the form of glycosylated conjugates. The main flavonols in onions are quercetin- 4 -O-glucoside and quercetin-3,4 -0-,diglucoside with smaller amounts of isorham-netin-4 -0-glucoside (Fig. 1.3) [Mullen et al., 2004]. [Pg.5]
