Preliminary Phytochemical Screening, Free radical Scavenging and Antimicrobial activities of Citrus auranticum fruit bio-mass

The present study was undertaken to evaluate antioxidant activity and antimicrobial activity of methanol extracts of gamma irradiated and unirradiated Citrus auranticum fruit bio-mass. In-vitro antioxidant activity has been investigated by 1,1-Diphenyl, 2-picryl-hydrazyl free radical scavenging method. The extracts were subjected to antibacterial (Staphylococcus aureus, Escherichia coli, Salmonella typhi) and antifungal (Aspergillus niger and Candida albicans) screening by disc diffusion method. Preliminary phytochemical investigation was done and different phytoconstituents present were identified.
