Introduction: Green leafy vegetables are an excellent source of bioactive compounds beyond human nutrition. There are many underutilized vegetable leaves which are equally a power house of bioactive compounds with reference to antioxidants. Much literature confirms that brassicca vegetables are high in antioxidants but the antioxidant studies these vegetable leaves are scarce as they are underutilized and neglected hence the present study was framed. Aim: To analyze the total antioxidants, total phenols and total flavonoids in the leaves of cauliflower radish and beetroot leaves. Methodology: Total antioxidants were analysed using Dpph method and phenols by Folin-Ciocalteu method and Total flavonoids were determined spectrophotometrically. Results: The observations were read in triplicates. The data was analyzed statistically showing the presence of total antioxidants, total phenols and total flavonoids in leaves of cauliflower radish and beetroot which can a therapeutic role in the health of humans. Conclusion: Hence the present study reveals the benefits of these underutilized leaves which are packed with antioxidants that can prevent from all degenerative diseases and these antioxidant leaves can be also treated in formulation of functional foods and in food and health industry.
