title: [Determination of flavonoids in natural materials with HPLC].
abstract: The paper reviews recent developments in the determination of flavonoids with HPLC. Flavonoids are a group of polyphenolic compounds commonly found in plants. Sample preparation is a very important step in the analytical procedure. The basic concept of a sample preparation method is to convert a real matrix into a sample in a format that is suitable for analysis by separation or analytical technique. In the present paper, attention was focused on the applications of molecularly imprinted polymers, especially on their utilization as selective sorbents in solid-phase extraction in the determination of flavonoids.
