Investigation of the effects of different organosolv pulping methods on antioxidant capacity and extraction efficiency of lignin

► Applying lignin extraction efficiency to evaluate four organosolv pulping methods. ► 1,4-Butanediol method has the highest lignin extraction efficiency. ► Lignin from acetic method was the most effective free radical scavengers. ► Pulping methods influence pulps morphology, pulps properties and lignin structure.
