Abstract

Seeds from Solanum sisymbriifolium Lam harvested at Olavarría (Buenos Aires, Argentine) were defatted with hexane and the raw oil obtained with a yield of 20,6 % dry basis. The physicochemical characteristics of crude oil were: refractive index: 1,4610 (at 25ºC), iodine value: 112,8; saponification index: 170,0; unsaponifiable matter: 14,0 % and free fatty acid content: 2,4 (mg KOH/g). The fatty acid composition of seed oil was studied by gas-liquid chromatography. Major fatty acids of seed oil were: linoleic (52,3%), oleic (23,4 %) and palmitic acid (16,4 %). The residual seed meal contained moderate level of crude protein (14,75%, dry basis), low level of available lysine (2,25 g/16gN) and high content of crude fiber (51,5%, dry basis). Total and phytic acid phosphorous, calcium, ash, sugar and polysaccharides contents are reported.
