Dialium guineense is an important medicinal plant used in fighting diverse diseases because of the presence of vitamin c it contains. This study is aimed at varying the vitamin composition of Dialium guineense fruit pulp obtained from four accessions from different geopolitical locations (South-West, South-South, South-East, North-Central) in Nigeria. Different vitamins were considered which includes; Vitamin A, Vitamin B12, Vitamin C and Vitamin E. The vitamin composition of D. guineense fruit pulp were done according to the standard biochemical method. The result obtained for all the four accessions shows varying quantities in the vitamins investigated. Vitamin C has the highest amount in varying quantities with the trend: North-Central (Abuja) ? South-South (Edo) ? South-West (Oyo) ? South-East (Abia), while Vitamin A: North-Central (Abuja) ? South-West (Oyo) ? South-South (Edo) ? South-East (Abia), Vitamin B12: South-West (Oyo) ? North-Central (Abuja) ? South-South (Edo) ? South-East (Abia), and Vitamin E: South-South (Edo) ? South-West (Oyo) ? North-Central (Abuja) ? South-East (Abia). These accessions of D. guineense were high in Vitamin C, followed by Vitamin A, then Vitamin E, and Vitamin B12. The presence of all these vitamins are good indices that D. guineense is a very rich nutritional and medicinal plant with high potentials of vitamin content considering different accessions.
Contribution/ Originality
The paper’s primary contribution is finding how provenance/accession could alter the genetic make-up and vitamin composition of Dialium guineense. Since vitamin C is the main components of Dialium fruits, the experiment is set up to investigate how provenance could affect the different vitamin composition of Dialium fruit.
