title: The Content of Secondary Metabolites and Antioxidant Activity of Wild Strawberry Fruit (Fragaria vesca L.).
abstract: Chemical analyses carried out in 2011-2013 aimed at evaluating the contents of flavonoids, free phenolic acids, tannins, anthocyanins, and antioxidant activity (%) by means of DPPH radical neutralization ability in fresh and air-dried fruits of three wild strawberry cultivars. Examinations revealed differences in contents of biologically active substances determined in raw versus dried material depending on the cultivar. Mean concentrations of flavonoids and tannins were highest in raw fruits of "Baron von Solemacher" cv., which amounted to 1.244 mg·g(-1) and 6.09%, respectively. Fresh fruits of "Regina" cv. were characterized by the highest average content of phenolic acids and anthocyanins: 4.987 mg·g(-1) and 0.636 mg·100 g(-1). The pattern of mean contents of biologically active substances analyzed in air-dried fruits was similar. Significant differences in abilities to neutralize the DPPH radical to diphenylpicrylhydrazine by extracts made of examined wild strawberry fruits were also indicated.
