ABSTRACT
The study investigated the nutritive elements of four species of Basella and two other commonly eaten
vegetables (Amaranthus hybridus and Talinum triangulare). The vegetables are found throughout the year. The
mineral compostion of the vegetables was carried out using standard procedures to determine which of these
would be of more health benefit to the consumers. Leaves were collected at the initiation of flowering and air-
dried under shade for 7 days after which they were kept in an oven at 60
o
C for 24 hours. These dried materials
were mechanically powdered and stored in airtight containers until used for analysis. The phosphorous content
of the vegetables ranged from 83.95±0.01 to 136.30±0.01 mg/100g. The potassium content ranged from
733.20±17.7 mg/100g to 4084.20+0.03 mg/100g. Sodium content in the vegetables ranged from 89.25±0.04 to
241.50±0.02 mg/100g. Zinc content ranged from 8.00+2 mg/100g to 28.90+4 mg/100g. The mineral contents of
the Basella forms are comparable to Amaranthus hybridus and Talinum triangulare. Overlap observed in the
values of the nutrient elements suggests interspecies relationship. Copper was present in Basella rubra and
Amaranthus hybridus, while Molybdenum was absent in all. This study revealed that the consumption of these
vegetables is dependent on the dietary need of the users.

INTRODUCTION
Green leafy vegetables are important in
the diet of Africans and Nigerians in particular
because they are rich in essential nutrients and
energy. They contain both essential and toxic
elements over a wide range of concentrations
(Okorondu et al., 2013) which can be
successfully utilized to build up and repair the
body as well as maintain alkaline reserve of
the body (Okolo et al., 2015). They also act as
buffering agents for acidic substances
produced during the digestion process (Badau
et al., 2013. Most vegetables add taste and
flavour to the monotonous starchy foods and
some are rich in essential oils, glycosides and
pigments which stimulate appetite. The large
number of species and varieties of vegetables
are raw materials for preparing a variety of
soups, thus, improving the range of enriching
food. The chemical composition of vegetables
shows high water content, sugars, protein,
