Originální abstrakt

DPPH is a free radical commonly used in antioxidant assay. A purple coloured solution which becomes colourless after reaction with antioxidant is convenient to spectrofotometric analysis. Unfortunately, there are many protocols providing different results, so we are unable to compare them among laboratories. We tried to examine presumptions about stability of DPPH molecule as a common condition for many protocols. Using different temperatures and antioxidants (ascorbic acid, salicylic acid, homocysteine, etc.) we found out that some presumptions are wrong.
