Techniques for maximising the extraction of nitrogen from the West African locustbean seed ( Parkia filicoidea Welw.) have been investigated. Maximum extraction (93 %) of nitrogen was obtained using a meal:solvent ratio of 2% with 0.05M NaOH. However, from the economic viewpoint a meal:solvent ratio of 1% using 0.01M NaOH would be cheaper. This ratio extracted 82% of the seed nitrogen. Other solvents such as sodium chloride solution and calcium hydroxide were not as efficient.
