Rapeseeds (Brassica napus L.)were germinated at $25^{\circ}C$ for 60 hours under dark condition in order to investigate the compositional changes in amino acids and fatty acids. The weight loss was most significant after 30 hours of germination and root growth was observed from that time. Analysis showed that Glu, Lys and Asp were the major amino acids and Ile was the limiting one. Germination caused an increase in Lys, Thr, Val and Leu while Met and Phe decreased among essential amino acids, resulting Met to be the limiting amino acid. The major fatty acids were oleic (49.3%), linoleic (22.0%) and eicosenoic (10.5%) acids. The decrease in oleic and stearic acids was measured while linoleic, linolenic, eicosenoic and erucic acids showed initial decrease followed by gradual increase.
