As it is widely known that the methods of extraction affect the qualities of oil, it is necessary to find out if these extraction methods affect the qualities of seed cakes as well. The aim of this article is to investigate the effect of extraction methods on the proximate, minerals and anti-nutrient composition of Huracrepitans seed cake. Three extraction methods (mechanical, Soxhlet and cold maceration) were employed using the methods of (Womeniet al., 2018) and (Nehdietal., 2010). The proximate composition of the seed cakes was determined using (AOAC, 2010) methods while their elemental mineral component was analyzed using Atomic Absorption Spectrophotometer (AAS) following (AOAC, 2016) methods, Sodium and Potassium was determined using Flame Photometer. Their anti-nutrient content was determined following the method of (Akaninwor and Okechukwu, 2004). The proximate composition showed that apart from the dry matter for the mechanically extracted seed cake which is 94% DM basis, the remaining parameters (crude fibre, crude protein, ether extract, energy content, and ash content) values were higher compared to the Soxhlet and cold maceration extracted seed cake. The mineral composition goes in the following order: (MEM>SEM>CEM) while the anti-nutrient content took the following trend: (CEM>SEM>MEM). This study has shown that methods of extraction also affect the qualities of seed cake as it does to the oil.
