“…24 Briefly, cranberry juice concentrate (7¥, 36 mL) was applied to an Amberlite XAD7HP-column (50 mL) and separated into the sugar/organic acid-rich and polyphenol-rich fractions by elution with 100 mL of water and then 100 mL of 70% ethanol. The fractions were vacuum-evaporated and freeze-dried before use in the experiments.…”

“…In addition, these non-ionic resins have been used in the analysis of terpenoid constituents of grape aroma from juices and wines (Gunata et al, 1985), in the isolation of octane 1,4-diol from apple juice (Schwab el al., 1989) and for debittering grapefruit juices by the adsorption of naringin and limonin (Shaw and Buslig, 1986;Wilson et al, 1989;Johnson and Chandler, 1982, 1988. In addition the resin Amberlite XAD-2 has been used recently in the analysis of flavonoids from honey and fruit jams (Ferreres et af., 1991;Tomas-Lorente et al, The aim of the present work was, firstly, a comparative study of the recovery of flavonoids from water extracts adsorbed by the different Amberlite XAD resins available in the market and, secondly, a study of the possibilities of differential desorption of the ad-…”

A comparative study of the recovery of flavonoids (both aglycones and glycosides) by different Amberlite XAD resins has been achieved. No significant differences in the percentages of recovery were found with the chemical nature and physical characteristics of the different resins. A flavonoid recovery higher than 90% is possible in a number of cases. The possibility of fractionating the adsorbed flavonoids by desorption with methanol: water mixtures has also been studied. The polystyrene resins (XAD‐2, XAD‐4 and XAD‐16) were found to be more useful for fractionation purposes than the polyacrylic resins (XAD‐7, XAD‐8). The results suggest that Amberlite XAD‐2 is the most suitable for the recovery and fractionation of flavonoids from plant extracts and foods rich in sugars and other polar compounds such as honey and fruit jams.

“…Fruit juice processing, particularly of citrus fruits, may increase the #avonoid content because the extraction process releases #avonoids from the rind of the fruit (Pierpoint, 1986). Su$cient #avonoids survive for the production of jams to use them in detecting adulterants in apple, apricot, peach, plum, sour orange, and strawberry jams (TomaH s-Lorente et al, 1992).…”
