Antioxidants are helpful in offering resistance against high production of free radicals in the body because of their ability to donate electrons that can neutralize the radical formation. This study identified and quantified the in vitro antioxidant and polyphenolic content from methanol extracts of three commonly available edible flowers of Allium cepa, Carica papaya and Cucurbita maxima by using several standardized antioxidant assay methods. The flowers were chosen as unconventional, yet an easily available source of potential nutritive value. Amongst the three flowers, at 500 µg/ml concentration in Ferric Thiocyanate (FTC) assay method, the methanol extract of Carica papaya showed better scavenging activity with the lowest IC50 of 17.47 µg/ml followed by Allium cepa umbel with IC50 of 37.06 µg/ml and Cucurbita maxima flowers in Superoxide radical scavenging assay at 500 µg/ml with IC50 of 56.06 µg/ml. Phytochemical analysis revealed the presence of higher quantity of phenols than flavonoids in the three flowers. Carica papaya recorded the highest amount of phenol content (108.66 mg GAE/100 g) and Cucurbita maxima with a slightly higher quantity of flavonoids (17.2 mg QE/100 g) which correlated with its antioxidant activity. It can be concluded that these flowers possess alleviating properties against reactive oxygen species-induced damage. |
