This review systematizes recent advances in the production, purification, and practical applications of extraction rosin, a naturally renewable product derived from the resinous softwood. The extraction technologies using organic solvents, alkali solutions, and supercritical CO₂ are considered. The methods for refining extraction rosin, which improve its colour, thermal stability and chemical purity, are described, including selective furfural extraction, adsorptive purification on bleaching clays and activated carbon, as well as chemical modification methods (hydrogenation and disproportionation) which allow improving its physicochemical characteristics. Rosin and its derivatives are widely used in both traditional industries (paper, paints and varnishes, adhesives, electrical engineering, etc.) and emerging high-tech areas, such as the synthesis of polymer composites, surfactants and biofuels. Owing to its biocompatibility, biodegradability and film- forming properties, rosin and its derivatives are increasingly employed in biomedicine for the development of controlled drug delivery systems, antibacterial and biodegradable coatings
