The aim of this investigation was to determine the genetic and chemical variability of raspberry growing wild in Poland. HPLC was applied for determination of phenolic compounds. The RAPD analysis indicated genetic variability of investigated populations. Chemical analysis revealed differences in the total content of flavonoids, phenolic acids and tannins in the leaves and roots. Flavonoids, namely quercetin, hyperoside, rutin, kaempferol, and isorhamnetin derivatives (isorhamnetin-3-glucoside and isorhamnetin-3-rutinoside) were found only in the leaves. Five phenolic acids were also identified, i.e., caffeic, chlorogenic, ellagic, rosmarinic and gentisic acids. Roots of red raspberry were richer in phenolic acids than leaves.

Key words: raspberry leaf, raspberry root, phenolic compounds, HPLC, RAPD
