The bark biomass is then partly used as a fuel (pellets), burned in furnace or recycled as mulching material. Despite its usage as an energy source, the bark also represents significant source of various chemical substances, which can be utilized by chemical, pharmaceutical or food industry and could add value to current utilization of this by-product. In our study, we monitored concentration of phenolic acids, selected flavonoids and maltol in water and methanolic extracts from young bark of two economically important coniferous trees harvested in Czech Republic: larch (Larix decidua) and scots pine (Pinus silvestris). The analysis of the extracts prepared by simple and inexpensive method confirmed the presence of several chemical compounds of industrial importance.
