In vitro antioxidant activity of extracts from leaves and fruits of common dogwood (Cornus sanguinea L.)

This paper deals with first new data for comparative analysis of leaves and fruits from common dogwood (Cornus sanguinea L.). Antioxidant activity is expressed as IC50 values (mu g/ml) that ranged from 1202,85 to 19,84 mu g/ml. The total phenolic content ranges from 27,45 to 205,74 mg GA/g. The concentration of flavonoids is between 14,40 and 118,46 mg RU/g. In comparison, methanolic and water extracts from leaves show significant antioxidant activity, IC50 values of this extract are better than the values for the G. biloba extract. The report of our research of plant parts from C. sanguinea can be regarded as promising candidates for natural plant sources of antioxidant with high value.
