Abstract
Optimization of the extraction time of rutin and quercetin from herbal plant (Inflorescentia tiliae, Violae tricoloris herba, Anthodium arnica, Flos sambuci, Herba rutae, and Herba hyperici) is described. Determination of aforementioned flavonols was performed by pharmacopoeial, spectrophotometric, and chromatographic methods. The highest quercetin concentration was obtained for Inflorescentia tiliae whereas Herba hyperici contains the highest amount of rutin. The methods were tested on pharmaceutical preparations. The obtained results were compared by statistical test.
