Abstract

Four populations of roseroot (Rhodiola rosea and Rh. quadrifida) originating from Poland and Mongolia were compared in respect of the content of main biologically active phenolic compounds (salidroside, p-tyrosol, trans-cinnamic alcohol, rosarin, rosavin and rosin) in the underground organs. Three solvents (75% ethanol, methanol and water) were used for the extraction of these phenolic compounds. Rh. rosea grown in Poland was characterised by similar content of salidroside and higher content of rosavin in comparison to the plants growing wild in Mongolia. The content of these compounds in Rh. quadrifida was lower than in Rh. rosea. Water appeared to be the best extraction medium for the isolation of salidroside and tyrosol. Cinnamic alcohol and its derivatives were more efficiently extracted with methanol and 75% ethanol.
