Abstract

Moringa oleifera seeds were evaluated for proximate and phytochemical components at three maturity stages of plant growth. Alkaloid content varied significantly (P<0.05) between the three stages. Alkaloid content (g/100gdm) increased from the 0.61 in 4thyear to 0.81 in the 6thyear and then decreased significantly (P<0.05) to 0.41 in the 7thyear of growth. Oxalate content (mg/100 g) decreased non-significantly (P>0.05) from 3.69 in 4th to the least concentration of 3.0, in the 6thyear of growth and then increased significantly (P<0.05) to 3.38 in the 7thyear. Saponin decreased from 4.15 in 4th to 2.05 in the 6th year of growth and then decreased further, but to 1.74 g/100gdm, in the 7thyear. The decrease was significant (P<0.05) between the 4th and 6thyear, but not significant (P>0.05) between the 6th and 7th year of plant maturity. TanninĀ  content (mg/100g) increased significantly (P<0.05) from 1.79, in 4th year to the highest level of 13.71, in the 6th year and then decreased significantly to 5.12 in the 7thyear of plant growth. Mean values of proximate composition (g/100g) ranged from 32.80-43.33Crude protein, 3.46-6.31Ash, and 10.46-17.42 carbohydrate. Crude fibre values were 6.36-8.20, lipid: 21.03-30.36, and moisture: 9.15-9.37. Crude fibre, ash, protein and moisture levels were significantly (P<0.05) higher at the 6th than at 4th and 7th year of maturity. It is recommended that moringa seeds be exploited as supplements in nutrition and health.
