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.
