Objective: Antioxidant activity of natural compounds in food and in
dietary supplements plays an important role in healthy life. Scientific
evidences suggest that antioxidants reduce the risk for chronic diseases
including cancer, diabetes mellitus and heart diseases.
Methods: The antioxidant activity of wild Cyclamen persicum, Malva
sylvestris and Urtica pilulifera leaves and their cultivated species
were studied using 2, 2-diphenylpicrylhydrazyl (DPPH) radical scavenging
activity and compared to Trolox antioxidant activity. The exhaustive
extractions yields for these samples were estimated by using polar and
nonpolar solvents.
Results: The results showed that the wild Cyclamen persicum, Malva
sylvestris and Urtica pilulifera leaves have higher exhaustive
extraction yield and as well the higher antioxidant activity (IC50)
comparing with their cultivated species.
Conclusions: Both of cultivated, as well the wild natural growing forms
of Cyclamen persicum, Malva sylvestris and Urtica pilulifera are a good
source for natural foods supplements, pharmaceutical industry purposes
and for organic food rich with antioxidant compounds.
