Zusammenfassung:	The Mediterranean stone pine Pinus pinea L. (gymnosperm, Pinaceae) is much appreciated for its seed production, widely used in food preparation in the Mediterranean Basin. Seeds contain 25% proteins on a dry-weight basis. Pinus pinea accumulate globulins as major storage proteins in seeds (75% of total storage proteins), composed of several subunits of 10 to 150 kDa, revealed by SDS-PAGE. The albumin fraction (15%) represents three subunits of 14, 24 and 46 kDa. Glutelins, the least soluble fraction, represents a small proportion (10%). Their constitutive units have frequent PM of 43 kDa. Prolamins also represent a very small percentage (1 to 2%).
