Abstract:
The present study focuses on two ornamental species of the Asteraceae family and their biological properties, which can be
correlated with the presence of different classes of natural compounds. Given the fact that secondary metabolites found in
such plants can be used as valuable resources for the pharmaceutical industry, we chose to investigate the biological potential
of Chrysanthemum indicum and Tagetes erecta inflorescences. Four types of extracts were obtained for each species, using
organic solvents with different polarities. Bioactive compounds such as polyphenols were quantitatively analysed using a the
Folin-Ciocâlteu method. The investigated compounds were present in all types of extracts in variable quantities, the highest
amounts being found in the methanolic extracts. Positive dose-related values revealed that the investigated extracts exhibit
good inhibitory activity against 15-lipoxygenase and a moderate metal-chelating activity. Moreover, all extracts showed
promising antibacterial and antifungal activities on the tested strains.
