The leaves and fruits of five Carica papaya morphotypes were harvested from trees in home gardens in Umuahia, Abia state, Nigeria. The morphotypes were based on fruit shape and pulp colour and are oblong red, oblong yellow, pear orange, round orange and round yellow. Seeds were extracted from the fruits and the proximate, mineral and vitamin analysis carried out on the leaves, fruits and seeds. All the determinants were carried out in triplicates. The result showed that there was a highly significant difference (P< 0.01) for proximate, chemical and vitamin compositions of theses morphotypes. The leaves had more crude protein, carbohydrate, crude fibre, Ca, Mg, Fe, and K than the fruit pulps and seeds. Beta-carotene was the most abundant vitamin in these Carica papaya morphotypes while papain activity was detected only in the leaves.
