Аннотация

Electrochemical behavior of β-carotene in polar organic media and solubilized systems has been investigated. β-Carotene is irreversibly oxidized at at 500 and 920 mV on glassy carbon electrode in 0.1 M LiClO4 ethanol containing 10 % of CH2Cl2. Effect of surfactants (caionic, nonionic and anionic) on voltammetric characteristics of β-carotene oxidation has been evaluated. High concentrations of surfactants facilitate the electrooxidation of β-carotene independently of surfactant type. The increase of oxidation current by 7-11 % has been obtained in presence of nonionic surfactant. The best results have been observed in 10 mM Triton X100 media. The peak current showed a linear dependence with the β-carotene concentration over the range 10-380 ?M. The calculated detection limit was 2.5 ?M and the quantification limit was 8.3 ?M. Liquid extraction of β-carotene with dichloromethane from raw vegetables and berries has been developed. Quantitative determination of β-carotene in real samples
