The search of prospective sources of biologically active compounds (BAC) remains an important commitment of Pharmaceutical science. One of most effective methods of the search today is chemotaxonomy.
Aim. The aim of this study was the establishment of correlations between morphologic features of 16 species of genus Asperula L. of family Rubiaceae Juss. and their certain chemical markers.
Methods. Previous research identified 177 morphological features and ecological characteristics of the given species. Identified by means of chromatography in the herb of the species under study were a number of chemical compounds related to flavonoids, coumarins and iridoids.
Results. Established is the corelation between the morphological features of genus 16 species of genus Asperula L.: A. odorata, A. arvensis, A. humifusa, A. Besseriana, A. aparine, A. rivalis, A. tinctoria, A. tyraica, A. campanulata, A. galioides, A. octonaria, A. cynanchica, A. supina, A. Stevenii, A. rumelica, A. praevestita and the presents in the herb of theese species of flavonoids – cosmosiine, isoroifoline, cynaroside, luteoline-7-arabinosylglucoside, hyperoside; coumarin umbeliferone; iridoids – asperuloside, asperulosidic acid, scandoside and monotropeine.
Conclusions. Within the 16 species of the genus Asperula it was established that the presence of BAC correlates with only a limited number of morphological features, namely: quadrangular stems; leaves with a sharp short apex, linear-lanceolate, rough with fine spreading hairs along the midrib and margins, pointed towards the apex; inflorescences apical; corolla white, four-lobes.
The data obtained can be used for a targeted search of BAC in the species of genus Asperula L.
