AB  - The composition and stability constant of the UO2(II)-hesperidin complex were determined by suitable spectrophotometric methods and pH-metric measurements. II was found that the uranil ion and hesperidin form a 1:2 complex in which the uranil ion is linked to the hesperidin molecule through the carbonyl and the 5-hydroxyl group. The relative stability constant, log K-2, ranged from 5.77 at pH 4.0 to 7.00 at pH 6.0. The conditions for the spectrophotometric determination of hesperidin, by means of reaction of the complex formation reaction, were investigated. Beer's law was obeyed up to 2.0x10(-5) mol dm(-3) hesperidin.

AB  - The composition and the stability constant of the Al(III)-hesperidin complex were determined by suitable spectrophotometric methods and pH measurements. The formation of the complex, whose concentration stability constant log K-1 ranged from 3.46 at pH=4.0 to 4.54 at pH=5.0, was established. The conditions for the spectrophotometric determination of hesperidin, by means of the complex formation, were investigated. It was found that hesperidin can be determined in the range from 2.50x10(-5)M to 1.75x10(-4)M. The application to the determination of hesperidin in orange juice is demonstrated. All investigations were carried out with 70% methanolic solutions at room temperature (20 degrees C), constant values of pH (3.7), and ionic strength (0.01).
