ABSTRACT
This study was undertaken to determine the anti-oxidant,
nutritional and anti-nutritional composition of Garcinia kola and
Chrysophyllum albidum from rainforest ecosystem of Ondo state, Nigeria.
The anti-oxidant analysis was performed for seed kernel, fruit pulp,
fruit skin and the whole fruit of Chrysophyllum albidum while
nutritional and anti-nutritional composition for the species were
performed for the fruit pulp and seed kernel. For Garcinia kola
nutritional, anti-nutritional and anti-oxidant composition was performed
on the seed kernel, fruit pulp and the fruit pod. Total phenol, total
flavonoid, Vitamin C and 1-1, diphenyl picaryl hydrazine (DPPH) were the
anti-oxidants determined for C. albidum and Garcinia kola. Analyses for
nutritional (moisture content, ash, protein content, crude fibre, fat,
carbohydrate) and anti-nutritional (phytate, oxalate tannin, alkaloid,
saponin, flavonoid) composition were conducted. The results showed that
moisture and ash content of the fruit pulp and seed kernel of C. albidum
were comparable; protein, fat and fibre contents were higher in the
fruit pulp than in the seed kernel while carbohydrate content of the
seed kernel was higher than that in the fruit pulp. For G. kola, the
fruit pod had higher ash content than the fruit pulp and seed kernel,
the fruit pulp had the highest moisture content, followed by fruit pod
and lastly by the seed kernel. The protein and fat contents of the seed
kernel and fruit pod were similar but higher than that of the fruit
pulp. Carbohydrate content was higher in seed kernel than in the fruit
pulp and fruit pod. The results of anti-nutritional analyses indicated
that the seed kernel and fruit pulp of G. kola and C. albidum did not
have high concentration of anti-nutrients. The fruits of the two species
were found to contain good amount of anti-oxidants. Thus, the
consumption of the two species is not detrimental health and they can be
used as food supplements in food manufacturing.
