Cichorium is effective for gastrointestinal diseases, also has a hypoglycemic effect. The optical properties of the extract phytodrugs have been little studied, although they may serve as a test assessing their qualities. The purpose of the research - is a determination of spectrophotometric parameters of the extracts from chicory, production pieces of its dry extracts and comparison with other inulin-containing plants. Methods. The researchers used Cichorium intybus, dry extracts from its roots produced in Russia and India, Helianthus tuberosus and Taraxacum of ficinale Wigg. Absorption optical spectra (AOS) were recorded on a digital spectrophotometer UV-2051PC. Results. There were obtained normalized AOS of infusions and tinctures of Helianthus tuberosus, dandelion roots, roots, leaves, flowers, seeds and production pieces of dry extracts of Cichorium roots. Conclusions. AOS of infusions in the subsoil parts of Cichorium, Jerusalem artichoke and dandelion are similar that indicate their commonality of substances. AOS of Cichorium roots extracts produced in Russia and India are the same indicating the identity of the substances in the final products. AOS of dry extracts solutions and infusions of Cichorium roots extracts roots are considerably different. Probably, when producing dry extracts from Cichorium roots, the substances ensuring the availability of spectral peaks are reacted, and the chemical composition is distorted.
