Abstract EN
Two Carthamus tinctorius varieties (Jawhara and 104) were studied in order to investigate their natural dyes contents and biological activities.
Obtained results showed that quinochalcone contents and antioxidant activities varied considerably as function of flowering stages.
So flowers at fructification stage contained the highest carthamin content with the strongest antioxidant capacity with all assays (FRAP, DPPH, and chelating power methods).
In parallel, we showed a decrease in the content of precarthamin.
The quantitative variation of these molecules could be due to colour change of C.
tinctorius flowers.
Correlation analysis indicated that the ABTS method showed the highest correlation coefficients with carthamin and precarthamin contents, that is, 0.886 and 0.973, respectively.
Concerning the regional effect, the contents of precarthamin and carthamin varied significantly P<0.05 at studied regions with the optimum production given by samples of Beja (902.41 μg/g DW and 42.05 μg/g DW, respectively, at flowering stage).
During flowering, the antimicrobial activity of these two natural dyes increased where the maximum inhibitory effect mentioned with carthamin mainly against E.
coli (iz = 25.89 mm) at fructification stage.
Therefore, the increased frequency of resistance to commonly used antibiotics leads to the search for new effective natural drugs at food and pharmaceutical industries.
