Proximate, vitamin and anti-nutritional properties of four forms of the genus Basella (Basellaceae) in South-western, Nigeria
摘要
Four forms of the Genus Basella Linn.; Basella alba Linn., Basella cordifolia Lamk, Basella rubra Rougx and Basella alba round exist in South western, Nigeria. All the members are consumed as leafy vegetables and are identified by the pigmentson the stems andleaves as well as the leaf shape. 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. They were evaluated for the percentage proximate, Vitamins and anti-nutritional properties using Standard methods. The concentrations of the proximate, anti-nutritional and vitamin constituents varied among the forms. 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 forms had Vitamin B2 contents (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 the vegetables are fair sources of nutritional parameters evaluated. 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.
