Abstract

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 (μg/ml) that ranged from 1202,85 to 19,84 μg/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.

Résumé

Cet article traite des premiers résultat d’analyses comparatives des feuilles et des fruits de cornouiller sanguin (Cornus sanguinea L.). L’activité antioxydante a été exprimée en valeurs IC50 (μg/ml) allant de 1202,85 à 19,84 μg/ml. Le contenu phénolique total se situe entre 27,45 et 205,74 mg GA/g. La concentration des flavonoïdes vaut de 14,40 à 118,46 mg RU/g. Par comparaison, les extraits méthanoliques et aqueuxdes feuilles ont montré une remarquable activité antioxydante, alors que les valeurs IC50 de cet extrait ont été meilleures par rapport aux valeurs des extraits de Ginkgo. Le rapport de nos recherches sur les feuilles et les fruits de C. sanguinea montre des activitiés prometteuses en tant que sources végétales naturelles d’antioxydants à haute valeur.
