- Abstract
The present study was aimed at comparing the locally produced vegetable oils (Mamador vegetable oil, Imo palm oil, Nsukka palm oil, Kings vegetable oil) with a foreign produced vegetable oil (Turkey vegetable oil), as to the levels of total flavonoids, total phenolic compounds, total glycosides and total alkaloids. In order to quantify and identify the aforementioned antioxidants, GC model of GC SR18610 Gas chromatography FID/ECD was employed. Kings vegetable oil was characterized by high content of total flavonoids (40.798 g/100g). Turkey vegetable oil was characterized by high content of phenolics (67.173 g/100g). Imo palm oil was characterized by high content of total alkaloids (39.194 g/100g), while Mamador vegetable oil was characterized by high content of total glycosides (40.511g/100g). However, the locally produced vegetable oil (Kings vegetable oil) presented important content of the four antioxidants: total flavonoids (38.141g/100g), total alkaloids (23.132g/100g), total phenolics (51.672g/100g) and total glycosides (19.730g/100g). According to the result, it is therefore suggested that the locally produced vegetable oil (Kings Vegetable Oil) can be used as specialty oil since it contains relatively high amount of the aforementioned antioxidants. However, the other vegetable oils under study such as Imo palm oil, Turkey Vegetable Oil, Nsukka palm oil and Mamador Vegetable Oil are all suitable for consumption since they contain reasonable amount of antioxidants.
