dc.description.abstract | Two hydroxyanthraquinones, alizarin and purpurin, that have been used throughout
history as a natural pigment, were extracted from roots of Rubia tinctorum from
Serbia. As substances with important chemical activities and, therefore, with wide
applications (for example in dyeing textile fabrics as well as in pharmacy because of
their anti-inflammatory, anti-cancer, antiviral, antimicrobial and antioxidant activities,
etc.) they were analyzed in the kinetically very sensitive Bray–Liebhafsky (BL)
oscillatory reaction. However, although they are both, hydroxyanthraquinones it is
shown that their interactions with BL nonlinear reaction system differ significantly.
Consequently, two different reactions were used to explain the mechanism of their
chemical activities. The numerical simulations based on a standard model of the BL
oscillatory reaction together with proposed reactions due to alizarin/purpurin interactions
with a matrix are correlated with experimental investigations. Moreover, it
is shown that very small amounts of alizarin and purpurin (from about 1 × 10–7 M)
produce the response of the BL matrix such that micro-quantitative analysis based
on the BL oscillatory reaction can be successfully performed in this reaction system.
The linear response of the BL matrix on the presence of alizarin and purpurin
(necessary for microquantitative determination) is analyzed as a function of two
concentration sensitive parameters: pre-oscillatory period τ1 and potential shift after
perturbation ΔE. | en |
