Abstract: Three different fractions of polysaccharides (PS1, PS2, PS3) were isolated from Ixora coccinea leaves to evaluate their antioxidant activity. The percentage of sugar in the extracted samples was checked by phenol- sulphuric acid method. 1, 1-Diphenyl-2-picrylhydrazyl (DPPH) assays and total antioxidant assay were done to evaluate its antioxidant property. The PS1, PS2, PS3 showed a % inhibition of DPPH radical at 43.21%, 31.11% and 24.23%. Total antioxidant activity was found to be higher in PS1. Both PS2 and PS3 showed almost equal antioxidant activity. The results of the present study indicates that polysaccharides from Ixora coccinea helps to overcome the untoward effects of oxidative stress, thus, contributing to the development of new drugs.
