Chlorogenic acid, rutin and hyperoside content in Fragaria vesca, F-viridis and F-moschata in Lithuania

In Lithuania, two species of the genus Fragaria L. (Rosaceae), F. vesca L. and F. viridis Weston, occur naturally in the wild and two others, F. moschata Weston and F.xananassa Duchesne ex Rozier are found escaped from cultivation. The main objective of this study was to establish the variation pattern in the content of chlorogenic acid, rutin and hyperoside in leaves and fruits of the native Lithuanian species. In this work, the chemical polymorphisms of different Fragaria species were studied by growing plants side by side under the same cultivated field conditions. F. vesca fruits had the highest rutin (1.38 +/- 0.19mg g(1) DM), hyperoside (0.69 +/- 0.10mg g(1) DM) and chlorogenic acid (2.25 +/- 0.34mg g(1) DM) content, followed by F. viridis and F. moschata. Our results showed that the leaves should be taken into account as important rutin and hyperoside contributors for strawberries.
