ABSTRACT

Natural antioxidants are widely distributed in flowers. The phyochemicals present in flower exhibit anti-inflammatory, anti-aging, anti-atherosclerosis and anticancer properties. The antioxidant activity of the polyphenols and flavonoids is due to the presence of phenolic hydrogen, which make them hydrogen donating radical scavengers. Among the 29 flowers studied, the phenolic levels ranged from 0.311±0.163mg TAE/g to 1.245±0.163 mg TAE/g. The phenolic levels was highest in Pelargonium peltatum (1.245±0.163 mg TAE/g) and lowest in Bellis perennis (0.311±0.163mg TAE/g). The flavonoid content was found highest in Pelargonium peltatum (0.385±0.001 mg AAE/g) and the lowest in Rosa hybrid and Celosia cristata (0.04±0.001 mg AAE/g). The highest antioxidant levels by FRAP assay were found in flower Pelargonium peltatum (0.982±0.033 mg AAE/g) and the lowest in Celosia cristata (0.118±0.012 mg AAE/g). The coefficient of determination was highest between total antioxidant levels and flavonoid content (R2 = 0.7919) followed by total antioxidant levels and TPC (R2 = 0. 6124) Keywords: Antioxidant, edible and medicinal plants from India
