AB  - 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.
