Comparative studies of the biochemical parameters of the leaves and seeds of Moringa oleifera was carried out to provide additional information on the nutritional status of the leaf and seed of M, oleifera. The vegetative and floral characters of the plants collected were examined, floral diagram and formular were recorded. Protein variation in the dry seed and leaf is an indication of protein polymorphism and this depicts the genetic divergence in the leaf and seed ofM. oleifera. Protein bands at 0.4, 1.1, 3.9 and 5.8 are taxonomically distinct, thus diagnostically separated the dry seed from other samples. Proximate analysis shows that the dry samples are more nutritious than the wet samples. 展开更多
