Abstract Four 8-hydroxyflavonoidglucuronides were isolated from the leaves of Malvasylvestris L. The structures of the two novel compounds gossypetin 3-glucoside-8-glucuronide and hypolaetin 4′-methyl ether 8-glucuronide were determined on the basis of spectroscopy and hydrolysis experiments. For hypolaetin 8-glucuronide and isoscutellarein 8-glucuronide spectroscopic data are given.
