Summary The chemical constituents of Pinus pinaster bark are studied, as a first step of a study devoted to its benefit. The analyzed samples showed an average content of 0.5% ash, 2.5% waxes (measured as the hexane and benzene soluble fractions), 39.3% of soluble materials in polar organic solvents, water and NaOH solutions, 28.9% polysaccharides (roughly half corresponding to cellulose), 29.6% Klason lignin, 59.7% aromatic content and 1.0% suberin. The fraction with potential utility, formed by formaldehyde-condensable polyphenols and polysaccharides, is over 60 weight percent of bark. The results are compared with those determined for other pine species.
