A series of experiments were conducted to investigate the structural composition of forage lignins, structural changes of lignins in the gastrointestinal tract, alkali delignification kinetics and the use of core lignin components as an internal marker. Three species were selected to represent different forage types; alfalfa (Medicago sativa L.), a temperate perennial legume, tall fescue (Festuca arundinacea Schreb.), a temperate perennial grass and coastal bermudagrass (Cynodon dactylon L. Pers.), a tropical perennial grass. Alkaline lignins soluble in 1,4-dioxane, from forage and feces, were isolated and characterized using /sup 13/C nuclear magnetic resonance spectroscopy and nitrobenzene oxidation.
