Abstract: Ricinus communis ( Minor) seeds used as an anti-conceptive drug in traditional medical practice in Nigeria have been analyzed for their amino acids and other constituents. Results showed high concentrations of fat (40.22%), crude fibre (22.05%) and protein (20.77%). Sixteen amino acids were obtained with concentrations of the essential amino acids comparing favorably with those of the FAO reference protein, whole hen`s egg and defatted soy meal. Thin Layer Chromatography (TLC) and Proton-Nuclear Magnetic Resonance analyses revealed the presence of sterols, unsaturated fatty acids and hydroxy fatty acids which may have implications in the anticonceptive attributes of Ricinus communis RC (minor).
