Abstract Root extracts fromUrticadioica were separated into several classes of compounds by extraction with organic solvents at different pH values. The phenolic fraction was analysed by GC-MS after trimethylsilylation. This procedure allowed the identification of 18 phenolic compounds as well as the detection of eight lignans. The occurrence of some of these substances in this plant was previously

starting point for valorisation of humins via preparation of humin-based ironoxidecatalytic nanocomposites from humins and thermally treated humins (foams) via solvent-free methodologies including ball milling and thermal degradation. The prepared materials were found to be active in the microwave-assisted selective oxidation of isoeugenol (conversions >87%) to vanillin, proving the feasibility to
