Abstract
The aim of the present study was to establish the correlation between the morphological features of 28 Bedstraw species (Galium L. genus, Rubiaceae Juss. family) and the content of flavonoids (cosmosiin, isorhoifolin, cynaroside, luteolin-7-O-arabino-glucoside, diosmetin-7-O-glucopyranoside, palustroside, diosmetin-7-Oxyloglucoside, nicotiflorine, hyperoside). Established was the correlation between the following: a glabrous stem, medium stem leaves borne in whorls of 6 to 8, corolla of 3 mm in diameter with lobes egg-shaped, and the presence of apigenin, luteolin and diosmetin derivatives. Conversely, these features do not correlate with the presence of quercetin and kaempferol derivatives. Only kaempferol glycoside (nikotiflorin) correlates with the such morphological features as creeping rhizomes, peduncle and pedicel hirsute. Only apigenin derivatives correlate with lobes oblong and fruiting pedicel glabrous. The data obtained can be used for a targeted search of biologically active compounds in the species of Galium L. genus.
