Traditionally, Cassia occidentalis flower has been extensively used to delicacy numerous infectious diseases. The aims of this examination were to determine the total phenol and flavonoid content of this plant using spectrophotometer; and assess the antioxidant and antibacterial possessions of the polyphenol rich fraction form flowers of C. occidentalis. The total flavonoid, and phenolic content assays showed that the polyphenol rich fraction had higher phenolic. The ABTS radical, Lipid peroxidation metal chelating, superoxide radical, nitric oxide scavenging and reducing power abilities and antibacterial activity were also evaluated. The flower polyphenol rich fraction revealed higher antioxidant properties of ABTS radical (72.31%), Lipid peroxidation (66.34%) metal chelating (78.32%), superoxide scavenging activity (71.56%) and Nitric oxide scavenging activity (81.45%). The antibacterial properties of the polyphenol rich fraction were analyzed by the disc diffusion method, and the flower extracts had higher antibacterial activities against the four bacterial strains used in the study. This study provides information on the synergistic antioxidant and antibacterial properties of phenolics derived from the flower parts of C. occidentalis.
