title: Quantification of anthocyanins in elderberry and chokeberry dietary supplements.
abstract: Elderberry and chokeberry food supplements may be 'functional food' in patients with metabolic syndrome or influenza but, for this, adequate amounts of co-active ingredients must be consumed in the daily dose. This study aimed to quantify the anthocyanin content in three elderberry and six chokeberry products to assess their usefulness as functional food. Analyses were carried out using an established HPLC procedure. The minimum anthocyanin doses for the treatment of metabolic syndrome disorders were estimated as 110 mg per day and 3.5 g per day for influenza. Three products were inappropriate for clinical use. The lowest liquid supplies were achieved with a proprietary elderberry concentrate (11 mL) and a proprietary chokeberry mother juice (100 mL). Clinical studies are now required to prove the effectiveness and adapt the doses according to the clinical symptoms.
