Chemical analyses aimed to evaluate the contents of free phenolic acids, flavonoids and tannins at different anatomical parts of three wild strawberry cultivars: ΄Regina`, ΄Rugia` and ΄Baron von Solemacher`, originating from agrotechnical experiments, were carried out at Department of Vegetable and Medicinal Plants, University of Life Sciences in Lublin in 2008–2009. The differentiation of determined biologically active substances depending on a leaf part was observed. Mean contents of phenolic acids and flavonoids were the highest at leaf blades of ΄Rugia` amounting 1.27% and 2.66%, respectively. No significant differences in tannins contents depending on a cultivar were recorded, although leaf blades accumulated significantly higher quantities of tannins than petioles.

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.

The qualitative and quantitative composition of essential oils obtained from whole leaves and inflorescences of two cultivars wild strawberry (΄Rugia` and ΄Baron von Solemacher` cv.) by means of steam and xylene distillation method, was compared. Material harvested at full flowering stage in 2008 and 2009 was subjected to study. Depending on a cultivar, air-dry inflorescences from wild strawberry contain from 0.21% (΄Baron von Solemacher` cv.) to 0.30% (΄Rugia` cv.), whereas leaves contains from 0.46% (΄Baron von Solemacher` cv.) to 0.62% (΄Rugia` cv.) of essential oils. GC/MS analysis of essential oils achieved from studied materials revealed presence of 70 (including 59 identified) compounds in leaves of ΄Rugia` cv. and 58 (including 50 identified) compounds in leaves of ΄Baron von Solemacher` cv. Essential oils from inflorescences of ΄Rugia` cv. contained 52 (including 47 identified), while ΄Baron von Solemacher` cv. contained 54 (including 46 identified) compounds. The chromatographic analyses by GC-MS revealed that myrthenol, nonal, linalool and phthalide dibuthyl dominated in essential oils obtained from leaves, while myrthenol, citronelol, linalool and geraniol – from those of inflorescences. There were qualitative differences between oil components at both studied materials and differentiation between both cultivars, as well.
