Simultaneous determination of rutin, hesperidin and quercetin contents in several solid dietary supplement samples is possible by HPLC method. The analysis process usedthe Agilent Zorbax Eclipse XDB C18 column (250 x 4.6 mm; 5 µm), a mobile phase composed of acetonitrile - phosphoric acid solution 0.1% with gradient program. The detection was carried out on a DAD detector at 280 nm for hesperidin and at 254 nm for rutin and quercetin. The limit of quantitation of method was at a low level of concentration (0.021g/100g with rutin, 0.047g/100g with hesperidin and 0.0054g/100g with quercetin); the accuracy of the method was within 97.0 - 101.33%; the precision showed 1.11 - 1.92% of relative standard deviation which showed high repeatability of the method. The method was applied to 20 dietary supplements samples, the results indicated a high level for the selectivity and reliability of the method to be applied.
