Chemical diversity within strawberry (Fragaria vesca L.) species

AGNIESZKA NAJDA, MAGDALENA DYDUCH

Abstract

The chemical diversity within wild strawberry (Fragaria vesca L.) species was studied depending on its origin (natural vs cultivated). The herb was collected at the full flowering stage. Following items were determined in collected material: flavonoids, phenolic acids, tannins, anthocyanins, as well as anti-oxidation activity (%) was evaluated by means of ability to neutralize the DPPH radicals. Contents of studied biologically active substances depended on the plant origin. Extracts made from examined raw materials showed no differences in the ability to reduce DPPH radicals to diphenylopicrylohydrazine. Key words: Fragaria vesca L., flavonoids, phenolic acids, tannins, anthocyanins, anti-oxidation activity, DPPH, phenotypic variability, genetic variability
