Composition and functional properties of essential oils extracted from forest waste biomass

Research output: Contribution to journalArticlepeer-review


Waste biomass from Eucaliptus globulus and Cistus ladanifer was subject to steam distillation to isolate the corresponding essential oils. The oils were analysed by gas chromatography and mass spectrometry in order to evaluate the concentrations of their main components. Both the essential oils and the water used in extraction of the distillates were evaluated for antioxidant activity, using the FRAP test and the DPPH test. Results showed that using this methodology it is possible to isolate significant amounts of essential oils (0.2 % to 0.3 % w/w) and obtain aqueous solutions containing phenolic components that may be used in the formulation of cleaning products.
