| Abstract: | The dioxane lignin (DLA) has been isolated from ripe stems of a cotton plant of the variety S-6524, and its empirical formula and molecular mass have been determined. This DLA differed from the DLA of a cotton plant of variety 108-F by a lower degree of hydroxylation and a higher degree of substitution of the aromatic rings.
