Abstract:
Aerial and underground parts of Geum rivale (Rosaceae) were investigated. Tiliroside, gallic acid, ellagic acid and a sterol fraction were isolated from aerial parts of the plant. The sterol fraction was analyzed using GC-MS. Eleven phenolic acids were identified in aerial parts of the plant, and eight in underground parts, by means of RP-HPLC analysis. The quantitative determination of phenolic acids, tannins and flavonoids was also carried out.
