Abstract

A high performance liquid chromatographic (HPLC) method with column-switching and diode array detection was developed for the determination of the flavonoids isoquercitrin, kaempferol, myricetin, quercetin, quercitrin, and rutin in three Finnish berry wines. Flavone was chosen as internal standard. Filtering was the only sample preparation before injection. The method wasapplied to the determination of the flavonoid profiles of wines made from black currants, blueberries, and crowberries. Myricetin, quercetin, and kaempferol were found in all three wines. In addition, the black current wine contained considerable amounts of rutin and isoquercitrin. The repeatability of the relative retention times was good (RSD less than or equal to 0.5%). Detection limits were less than or equal to 60 ng/mL.
