The compositions of biologically active substances in Euphrasia brevipila Burn. et Gremli (Scrophulariaceae) extracts obtained using solvents with different polarities have been investigated. It was established that the composition of isolated substances varied depending on the extractant polarity. Only phenolcarboxylic acids were found in ether, chloroform, and ethylacetate extracts. Aqueous, ethanol, and DMSO extracts contained also flavonoids and iridoids. The difference in the compositions…
