Biologically Active Substances of Rhei Tangutici Radices and Rhei Rhabarbari Radices

UDK: 615.322

The results of the comparative analysis of the qualitative composition and quantitative content of anthracene derivatives equivalent to istizin in Rhei tangutici radices, collect- ed in Central aimak (Mongolia) and Rhei rhabarbari radices collected in Buryatia (Russia) using spectrophotometry method, are presented in the article. Anthracene de- rivatives (emodins, methyl chrysazin), tannins, flavonoids, coumarins and fatty oils were qualitatively detected in all samples (using standart methods). The content of an- thracene derivatives in R. tangutici radices (2,2–3,0%) meets the standards of State Pharmacopoeia (not less than 2%), and R. rhabarbari radices fails to meet the re- quiremetns. (0.5-1.1%).
