GENERAL CHEMICAL-COMPOSITION OF SEEDS AND INFLORESCENCE FROM PLANTAGO-LANCEOLATA (LLANTEN)

Seeds plus inflorescence from Plantago lanceolata harvested at Olavarr ia (Buenos Aires, Argentina) were defatted with petroleum ether (60-de grees-80-degrees) and the raw oil obtained with a yield of 2,3% dry ba sis. The crude oil was examined in their physicochemical characteristi cs. It had refractive index of 1,4647 (at 25-degrees-C), saponificatio n index of 159,7, unsaponifiable matter of 29,9% and total sterol 6,3% (as sitosterol). The fatty acid composition was established 0,3);14:0 (1,8);14:1(3,1);15:1(0,4);16:0(45,7);18:0 (1.6); 18:1 (10,5); 18.2 (29 ,6); 18:3 (6,7). The residual seed meal contained 13,87% of crude prot ein, of available lysine 1.01 g/16 g N. Values of total phosphorous, a sh, crude fiber, calcium, polisaccharides (non presence of starch) and ''residual lipids'' are given.
