Abstract
Seventeen endophytic fungi were isolated from leaves and roots of Cymbopogon citratus. The endophytic fungal extracts were prepared using ethyl acetate and evaluated for their phytochemical constituents and extracellular enzymes using standard protocols. They were also subjected to Total Phenolic Content (TPC) and antioxidant potential. 76% of the isolates were found positive for flavonoids, 70% for terpenoids, Quinones and cardiac glycosides were seen in 41%. 70.5% demonstrated amylase activity, 58.8% protease and laccase activity, 41.1% lipase and chitinase activity and only 29.4% showed positive for cellulase activity. The TPC and antioxidant activity of the fungal cultures ranged from 14.29 to 65.5 mg TAE/g of dry weight and 11-60% of scavenging respectively. Among the 17 isolates, Fusarium oxysporum showed the strongest antioxidant capacity, having the highest phenolics concentration. The present work reveals that the metabolites produced by endophytic fungi can be a potential source of natural antioxidants and enzymes with pharmaceutical importance.
