Background: The natural antioxidant products in the plant
kingdom play an important role in the healthy life style and reduce the risk
for various chronic diseases. Objective: The objective of this study was to
investigate different antioxidant pharmacological property of methanol extract
for fifteen species of Campanula plant from Palestinian flora.
Methods: The antioxidant activity of fifteen Campanula species growing
wildly in Palestine were studied using 2,2-diphenylpicrylhydrazyl (DPPH)
radical scavenging activity and their antioxidant activity was compared to
Trolox antioxidant activity.
Results: The results clearly demonstrate a very high antioxidant
activity of the Campanula sulphurea and Campanula sidoniensis and they showed
almost the same antioxidant activity of Trolox. The other twelve species
extracts also exhibited excellent antioxidant activity in DPPH radical
scavenging activity in comparison with trolox standard.
Conclusion: Methanol extract of Campanula can be valuable for treatment
of different diseases and could be used as a possible new source of natural
antioxidants in the food, nutraceuticals, pharmaceuticals and cosmetic
industry.
