Because the flax and hemp fibers contain phenolic acids in their chemical composition, they show antioxidant activity, which is presented in **Table 3**. The fiber antioxidant activity depends on the type and variety of fibrous plant as well as on the method of fiber extraction [30]. The highest value of ferric reducing antioxidant power (FRAP) and value of 2,2,2-diphenyl-1-picrylhydrazyl (DPPH radical) scavenging activity illustrating antioxidant activity of the fibers were found in all types of fibers after decortication because the fibers contain the largest amount of phenolic acids.
