Phenolic acids and coumarins were investigated chromatographically. The structures of the compounds were established on the basis of acid hydrolysis and spectroscopic methods (UV, 1H-NMR, 13C-NMR) as hypolaetin 8-glucoside and the new flavonoid sulphate - isoscutellarein 4′-methyl ether 8-glucoside-2″-SO3K. Key words Althaea officinalis - Malvaceae - hypolaetin 8-glucoside - isoscutellarein - 4′-methyl ether 8-glucoside-2″-SO3K PDF (168 kb)
