Comparative Analysis of the Antioxidant Activity of Cassia fistula Extracts.
Antioxidant potential of various extracts of Cassia fistula was determined by the DPPH, FRAP, Fe(3+) reducing power, and hydrogen peroxide scavenging assay. Methanolic extracts of Cassia fistula showed the highest amount of phenolic and flavonoid content and reducing capacity, whereas hexane extracts exhibited the lowest level of reducing capacity. The order of antioxidant activity in Cassia fistula extracts displayed from higher to lower level as methanolic extracts of pulp, methanolic extracts of seed, hexane extracts of pulp, and hexane extracts of seed. The antioxidant potential of Cassia fistula extracts significantly correlated (P < 0.02) with the phenolic content of the methanolic extracts. Ascorbic acid taken as control showed highest antioxidant power in the present study.
