Proximate and Anti -Nutritional Properties of Four Forms ofthegenusBasella (Basellaceae) in South-western, Nigeria

Abstract

Background Three species and a land race of the Genus Basella Linn. namely; Basella alba, Basella cordifolia, Basella rubra and Basella alba round exist in Nigeria. All the members are consumed as leafy vegetables. The aim of this study is to find out which of the Basella forms is more nutritious and the levels of the ant-nutritional components. Results from this study will add to our knowledge of the Basella species and also form the basis for recommendations to be made to farmers on the species to increase its cultivation and consumption. Methods They were evaluated for the percentage proximate, Vitamins and anti-nutritional properties using Standard methods of the Association of Official Analytical Chemists. Results The concentrations of the proximate, anti-nutritional and vitamin constituents varied among the species and the land race. B. alba had the highest moisture (98.00 ± 0.01%), crude fibre (0.59 ± 1.01%) and Ash (33.39 ± 2.11%) contents. B. rubra had the highest protein (3.64 ± 0.01%) and Vitamin E (0.50 ± 0.02%). B. cordifolia had the highest fat content (0.68 ± 1.03%). the species had Vitamin B1 content (2.00 ± 0.02%) except B. alba round (1.50 ± 0.02%). The percentage of proximate, Vitamins B2 and E contents were within required limits and are excellent sources of Vitamins. Conclusion The anti-nutrients were within the safe limits. Cyanide and Mercury were not detected in all the forms. All the vegetables can be planted and consumed depending on the need of the consumers.
