Chemical profile of Landolphia owariensis seed from Ikeduru, Imo State, Nigeria
The nutrient, antinutrient and mineral element compositions of the seed extract of Landolphia owariensis were investigated. Proximate analysis of the extract showed that it contained crude protein (11.85+0.35% DW), fat (17.40+0.20% DW), carbohydrate (52.40+0.40% DW) and fibre (3.5+0.30% DW). The toxicant composition of the seed extract revealed that phytate, oxalate and cyanogenic glycoside contents were 48.15+0.05, 56.01+0.02 and 33.20+0.01 mg/100 g DW respectively while the phytochemical composition revealed that tannins, saponins, alkaloids and flavonoids were 100.50+0.30, 28.40+0.20, 1.90+0.08 and 1.50+0.25 mg/100 g DW respectively. Mineral element concentrations also revealed that the seed is a rich source of macro and micro elements containing calcium 110.20+0.10, potassium 205.04+0.1.50, sodium 48.02+0.20, iron 9.50+0.40, phosphorus 20.08+0.05 and magnesium 2.91+0.05 mg/100g dry weight respectively.
