ABSTRACT
The current research provides the development of the new spectrophotometric
method for the simple and affordable quercetin quantification. Proposed
method based on formation of supramolecular assembles of quercetin (Q) and
cetyl trimethylammonium bromide (CTAB). Under selected experimental
conditions (l = 378 nm, cCTAB = 2 mM and T = 25 °C), Beer’s law was obeyed
in the quercetin concentration ranged 2 ¥10-6 - 8¥10-5
mol dm-3. The method
sensitivity was 2.1 × 104
dm2
mol–1
(the molar absorptivity) as well as 1¥10-6
mol dm-3 (the limit of detection). The method applicability to the direct Q
determination in a pharmaceutical formulation (Quercetin+C capsules,
Twinlab) was demonstrated.
