Abstract
There is a constant need for novel antibiotic and antioxidant sources due to the ever-increasing resilience of pathogens and the occurrence of chronic diseases. The natural sources of these agents have advantages due to lower production cost, structural variation, and uses of active compounds for pharmaceutical uses. The microbes living in planta termed “endophytes” are alternative sources of host bioactive compounds. In this study, ten endophytic fungi were isolated from Polygonum chinense L. and identified by sequencing of the internal transcribed spacer regions. The fungal strains were fermented and the ethyl acetate extracts were evaluated for antimicrobial and antioxidant capacities. Almost 80% of the endophytes showed antibacterial potency against one or more pathogenic bacteria. Among all strains, Penicillium canescens showed broad-spectrum antimicrobial activity against gram-positive and gram-negative pathogens as well as significant antioxidative and DNA protective capacities. The strain Fusarium chlamydosporum displayed significant anti-radical (126.8 ± 6.7 μg/ml) and ferric reducing (84.7 ± 2.1 mg AA/g dry extract) capacities. The bio-autography, chromatography, and mass spectroscopy analyses of P. canescens extract revealed the presence of sesquiterpene (germacrene), plasticizer (phthalic acid ester) along with phenolic acids, flavonoid (quercetin), and short chain hydrocarbons. The secondary metabolites of F. chlamydosporum were identified with phenolic acids as bioactive compounds by chromatography and mass spectroscopy. This study indicates P. chinense endophytes as potential sources of antimicrobial and antioxidant compounds for novel drug discovery.
