CHEMICAL-COMPOSITION OF RUMEX-CRISPUS L SEED

Rumex crispus L. seeds harvested in Olavarria (Province of Buenos Aire s, Argentina) were extracted with 60-80 degrees C petroleum ether to r ender 6.0% (dry basis) of a lipid fraction with a 152.4 saponification value and 15.4% unsaponifiable matter. Fatty acid composition obtaine d by gas-liquid chromatography was: 14:0, 2.7; 16:0, 13.5; 16:1, 1.2; 18:0, 1.2, 18:1, 38.6; 18:2, 36.3; 18:3, 0.5; 20:0, 2.4; 20:2, 0.3; 22 :0, 0.9; 22:1, 1.2; and 24:0, 1.2; with traces of 14:1, 15:1, 17:0, an d 17:1. Residual meal contained 10.62% crude protein, with a low value of available lysine (3.31 g/16 g N). Ash, crude fiber, sugars, hydrol yzable carbohydrates, total and phytic acid phosphorus, calcium and re sidual lipids contents are reported here.
