The phytochemicals produced by these fungi were, steroids, tannins, flavonoids and alkaloids. The endophytic fungi exhibited 2, 2-diphenyl-l-picrylhydrazyl (DPPH) scavenging activity; the highest percentage of free radical scavenging activity (RSA) was in Rhizoctonia sp. (52.34 ±2.5%) isolated from rootsand the lowest was in Aspergillus japonicus (16.52 ± 1.14%). 50% of endophytic fungi showed total phenolic content (TPC) and Rhizoctonia sp. (CAR7) exhibited highest TPC of 4.099 ±0.07 mg gallic acid/100 ml. TPC of endophytic fungal extracts were correlated with the DPPH scavenging activity. 收起
