This work was carried out with propose to evaluate the relation between structural profile of Björkman lignin and the malleability property of the xylem of Paullinia rubiginosa. The analysis was carried out by mean of 1H NMR and infrared spectroscopy methods. The methoxyl content was also determinated by 1H NMR method. The calculated value was of 18.97%. It revealed a high guaiacyl unit concentration in the Björkman lignin of Paullinia rubiginosa. The data suggest the existence of a rigid system for Paullinia rubiginosa lignin.
