Potentilla alba L. (Rosaceae) is perspective plant for different the treatment of different diseases especially thyroid gland. Phytochemical study of P. alba rhizome 3-rd and 4-th years old plants cultivated under original technology with application of natural organic fertilizer «Biogumus» was done. Phytochemical evaluation of the samples by various analytical me­thods (AAC, HPLC, TLC, UV-VIS-spectroscopy, titrimetric and gravimetric) was performed. Rhizomes of P. alba 3-rd and 4-th years plants contain lipophylic compounds (0,21 and 0,25% respectively), significant amounts of substances dissolved in 95% ethanol (20,4 and 17,3%), 40% ethanol (41,0 and 36,0%), hot water (18,9 and 19,5%) and 1% NaOH (25,3 and 34,8%). Polyphenols (50,0 and 33,0%) and phenolic acids (1,1 and 1,0%) were the main groups in 95% ethanol fraction. Polyphenols (4,3 and 4,6%), polymeric (1,2 and 1,0%) and monomeric (0,27 and 0,34%) antocyanidins and trace amounts of flavonoids (0,18 and 0,13%) were determined in 40% ethanol fraction. Tannins (21,9 and 20,5%), amino acids (19,5 and 14,3%) and polysaccharides (4,5 and 5,2%) were dominant groups in water fraction. Thus, three years of cultivation is enough for qualitative biomass reception and biologically active compound accumulation. Results of macro- and microelement analysis of the samples show that the plant actively accumulates magnesium, calcium, potassium, phosphorus, iron and manganese and contains insignificant quantity of iodine
