Popis: Lignin plays a crucial role as a structural material of plant cell walls and is also known as a significant renewable resource that has the potential to be a raw material for producing high value chemicals. The article aimed to research on the extraction of lignin from sugarcane bagasse by environmental method using deep eutectic solvents (DESs) containing choline chloride and formic acid. In the process, lignins dissolved in DESs were isolated from the solution by dilution with water and ethanol. The obtained lignin samples were characterized with UV - Vis (Ultraviolet – visible spectroscopy), FT-IR (Fourier-transform infrared spectroscopy), GPC (Gel permeation chromatography), and 1H-NMR (Proton nuclear magnetic resonance). The initial results showed that the extracted lignin obtained adequately distinct functional groups and the weight average molecular mass of the lignin was about 28265 g/mol.
