ABSTRACT
The vitamins content of onion bulb and garlic rhizoids was analyzed in this study to compare the level of Vitamin A, C and E. Standard analytical procedures was employed and followed strictly for the accurate determination of the vitamin concentrations. From the results, vitamin C recorded the highest concentration of 36.25 ± 0.077 mg/100g followed by vitamin E (2.42 ± 0.189 mg/100mg) and vitamin A (1.84 ± 0.045 mg/100g) for onion, while highest concentration was also recorded for Vitamin C (28.09 ± 0.089 mg/100g followed by vitamin A (3.12 ± 0.045 mg/100mg) and vitamin E (2.52 ± 0.189 mg/100g) for garlic. However, the concentrations of vitamin A and E were higher in garlic than in onion. The results thus indicate that the spices are fairly rich in dietary vitamins which could contribute greatly to human nutrition even though the concentrations were lower than the Recommended Dietary Intake (RDI).

1.0 INTRODUCTION
1.1 Background of the Study Antioxidant compounds in food are found to have a health–protecting factor. Primary sources of naturally occurring anti-oxidants are whole grains, fruits and vegetables. Garlic (AlliumSativum L.) is one of the most commonly produced Vegetables worldwide. Garlic is a source of various biologically active phytomolecules, including organosulfur compounds, phenolic acids, allylthiosultimates, flavonoids and vitamins.
