Chemical composition and the effect of extraction solvents on the antioxidant contents of Uchakuru (Vitex doniana) leaves gotten from Owelli-court in Awgu local government area of Enugu State:- Okolie, Martins C
ABSTRACT
The chemical composition and the effect of
different extraction solvents (water, acetone, ethanol and water-acetone
(50:50)) on the leaf extracts' antioxidant and antioxidant activities were also
analyzed. The results revealed that the proximate composition had 4.5, 16.21,
11.09, 4.07, 9.17, 54.89 and 321.09 Kcal for moisture content, crude protein,
crude fibre, fats, ash, carbohydrates and energy value respectively. Vitamins
A, B;, B;, By, B,, C and E were found to be present in the leaves with vitamin
C had the highest cponcentration (110.14 mg/100g). Mineral content showed
59.73, 8.71, 17.55, 45.05, 116.83, 18.63 and 3.93 mg/l00g for calcium, sodium,
magnesium, phosphorus, potassium, iron and zinc respectively. Antinutrients
values of 3.74, 0.92, 5.63, 8.92, 0.67 and 6.33 mg/l00g for alkaloid, tannin,
saponin, phytate, oxalate and glycoside respectively. The results showed that
V. doniana leaves are rich in flavonoids and phenolic constituents. The highest
total phenolic content of 451.03 mgGAE/g was obtained in water extract and
highest total flavonoid extraction of 302.92 mgQE/g in ethanol extract. The
antioxidant activities- (FRAP and ABTS) were strongest in ethanol extract,
(water 0.94, acetone 1.06, water-acetone (50:50) 0.77, ethanol 1.40), (water
61.03, acetone 32.78, water-acetone (50:50) 40.72, ethanol 66.31) respectively
while the DPPH activities was strongest in water extract. (water 88.29, acetone
50.17, water-acetone (50:50) 51.13, ethanol 54.07). Utilization of Vitex
doniana (uchakuru) leaves should be encouraged for use As food for its
nutrients and antioxidant properties to enhances the nutritional and health
status of the consumers.
