                  The last decades are characterized by a clear tendency of widespread use in the medical
             practice of natural active substances (NAS), the advantage of which is low toxicity, milder action,
             and a wide range of pharmacological activity. Modern research has proven the high efficiency of
             an important and sometimes predominant source of raw materials – plants from the arsenal of
             folk and traditional medicine, which determine the value of species for pharmacy and medical
             practice.  The  rational  ratio  and  composition  of  NAS  components,  similar  to  bioactive
             compounds of the body or products of its vital activity (metabolites), provide a harmonious
             relationship and interdependence of physiological and biochemical processes, which determine
             the diversity and widespread use of plants. A special group is represented   by organic substances
             volatile organic compounds (VOC) – a wide class  of natural metabolites that perform important
             biological and biochemical functions in living organisms, the relevance of the study of which has
             significantly increased in recent years.
                  This work aimed to study the specific biochemical characteristics of the VOC composition
             of the underground part of the introduced species of the Asteraceae Bercht.  & J. Presl family of the
             genetic collection of the M.M. Gryshko National Botanical Garden of the NAS of Ukraine and to
             assess the potential of bioactive ingredients. They preferred large burdock (Arctium lappa L.),
             common chicory (Cichorium intybus L.), medicinal dandelion (Taraxacum officinale Wigg), spread
             grindelia (Grindelia squarrosa (Pursh.) Dun), and common Georgina roots (Dahlia single L.). VOC was
             obtained  by  a  modified  method  of  hydrodistillation,  followed  by  gas  chromatography-mass
             spectrometric analysis (GC-MS) of their component composition, the quantitative content of which
             was calculated by the normalization method.
                  The VOC of the roots of the species under study refers to alcohols, aldehydes, saturated and
             unsaturated  hydrocarbons,  esters,  etc  (%).  Chicory  has  40  VOCs,  31  were  identified.  Ethyl
             palmitate (25.43) and ethyl linoleate (48.15) dominate. Borneol, bornyl acetate, cadinene alcohol,
             tetradecane,  ethyltetradecanoate  are  characteristic  of  this  species.  For  burdock,  out  of  45
             substances,  40  were  identified,  the  main  of  which  are  1,11,15-heptadecatriene  (25.34), 1,11,13-
             heptadecatetraene  (108.93),  hexanol  (49.31).  Ethyl  palmitate,  cis-,  trans-2,  4-decadienal,
             pentadecene-1, paracymene-8-ol, furfural were found to be a marker.  Dandelion was identified of 47
             substances. Heptadecene, еthylphenyl acetate were found to be specific VOCs. In dahlia tubers
             55  VOCs.  Major  1,3,5-tridecatriene-1-triine  (37.13)  were  identified.  Specific  components no
             more  than  1%.   Grindelia  had  76  VOCs  (%),  31  with a predominance of  alcohols  (%):  borneol
             (15.53), verbenol (8.22). Basic alkanes (28.35), terpenes (8.28) – germacrene B, characteristic-
             methylgrindelate. Special attention is paid to the presence of unsaturated carbon squalene – a
             powerful immunostimulant, the high level (%) of which is characteristic of the aerial part of
             dandelion  (5.62),  burdock  (6.27),  chicory  (17.33),  which  determines  their  prospects  for  the
             creation of anticancer drugs. The specificity of the component composition of VOCs suggests the
             possibility of developing diagnostic features to determine the species of the considered plants
             under consideration, as well as using their raw material potential to create multifunctional
             medicinal products.
