Phytochemical contents of Moringa oleifere seeds, stem bark and leaves were determined using various standard methods. The toxicological evaluation was carried out using brine shrimp lethality assay. The phytochemical and anti-nutritional evaluation of the samples revealed that the leaves were highest in alkaloids (6.68±2.35 %), saponins (35.66±0.78%) and tannins (0.64± 0.45 mg/100g), while the stem bark has the lowest contents with values of 0.53±0.25%, 14.3±0.33% and 0.56±0.17mg/100g, respectively. The seeds were however high in flavonoids (14.21±0.66%), oxalates (31.98±0.62mg/100g), phytates (0.85±0.04mg/ 100g) and cyanogenic glycosides (7.4±0.00 mg/100g).
The toxicological study also revealed that extracts from the three parts were not toxic after 24 hours. Mortalities however took place after 48 hours (between 1-5 nauplii death) and 72 hours (5-10 nauplii death) at varying concentrations.
