A quantitative analysis method for total anthracenderivatives in rhizomes et radices of Rubia tinctorum with the using of direct spectrophotometry at analytical wavelength 520 nm there was developed. The developed optimal conditions of extraction of anthracenderivatives in rhizomes et radices of Rubia tinctorum L. - extractant is 80% ethyl alcohol; the ratio of "raw-extractant" - 1:30; extraction time -90 min. The relative degree of the determination of the total anthracenderivatives in rhizomes et radices of Rubia tinctorum L. in developed method with confidence probability 0,95 is no more than ±3,18%. The content of total anthracenderivatvies in rhizomata et radices of Rubia tinctorum L. varied from 4,50±0,02% to 4,85±0,03% (calculated on ruberythrinic acid). © 2016, International Journal of Pharmacognosy and Phytochemical Research.
