ABSTRACT (Download PDF)
Vigna sesquipedalis was assayed to determine its content of essential minerals and vitamins that
are commonly associated with the ability to neutralize the damaging effects of free radicals and
consequently help prevent the development of cancer. Selenium, zinc, manganese, copper and
iron which have antioxidant capability were determined among other minerals. The antioxidant
vitamins, A, C, and E were also assayed among other vitamins. Appropriate colorimetric and
titration methods were used for assay of vitamins while the minerals were determined by means
of atomic absorption spectrophotometer. The results of the analyses showed that the seeds have
significant concentrations of vitamins A and C while vitamin E concentration was relatively low.
Also the minerals zinc, iron and manganese were significantly present while selenium and
copper were of relatively low concentrations. However, the antinutrients namely trypsin
inhibitor, haemagglutinin, and glycosides were found to be present. The results show that Vigna
sesquipedalis has significant concentration of substances that are effectively involved in free
radical scavenging and which can consequently enhance the body’s protection against cancer
development. The consumption of natural foods should be highly encouraged to reduce the
chances of development of cancer associated with increased consumption of industrially
Keywords: Vigna sesquipedalis, free radicals, antioxidants, vitamins, minerals.
