Extraction is the process of separation of a substance from a matrix and it can be done either mechanical extraction (expression) or chemical extraction (solvent). It could be liquid-liquid and solid-liquid phase extraction (Young et. al., 1994). In this work extraction of oil from seed was a solid-liquid extraction.

Ethanol is not a good solvent for oil extraction. It was used in this research work to prove the fact ethanol is a bad solvent for oil extraction and also to compare its extract from that of 17- hexane extract. The colour change of ethanol extract was as a result of the fact that ethanol bleached the pigments in the size- reduced groundnut.
