In vitro study on antioxidant and antibacterial effects of polyphenol rich fraction from flower of Ixora coccinea


S Chithra, K Vetrivel, Sivashankar Rangasamy

The present work was designed to search the possible antioxidant and antibacterial effect of the polyphenol rich fraction from flower of Ixora coccinea (Rubiaceae). The extract were tested against pathogenic bacteria, Escherichia coli, Pseudomonas Klebsiella pneumoniae, and Staphylococcus aureus by disc difusion methods. The content of phenolic compounds, flavones, and flavonols was measured. The antioxidant activities were evaluated using four assays: total antioxidant capacity, ABTS, lipid peroxidation, superoxide and nitric oxide scavenging. Antibacterial activity was studied using the agar disk diffusion method was determined. Results obtained showed a positive correlation between the antioxidant content of polyphenol rich fraction and the antibacterial capacity, polyphenol rich fraction were the maximum efficient against Gram-positive and Gram-negative bacteria. It is concluded that pollens can be a good source of bioactive molecules that exhibit potent antioxidant effects and strong antibacterial activities.
