Intraspecific chemical variability of wild growing roseroot from Southeastern Mongolian Altai was investigated. Five geographically distant populations were the objects of the study. The raw materials used for chemical evaluation were the underground organs (rhizomes with roots). The biologically active compounds in these raw materials were determined by HPLC, using the Shimadzu chromatograph with DAD detector. Nine phenolic compounds were identified: salidroside, p-tyrosol, rosavin, rosarin, rosin, trans-cinnamic alcohol, 4-hydroxybenzoic acid, caffeic acid and kaempferol. There were significant differences both between and within populations in respect of the content of these compounds. The content of rosavin, one of the main compounds, varied from 1 900.63 to 4 216.06 mg 100 g^-1 dry weight between the populations, and from 1 118.54 to 3 390.85 within the most abundant population.
