摘要

Endophytic fungi are significant sources of various bioactive natural compounds. The present work elucidates the antioxidant activity and chemical characterization of Campylospora parvula isolated from the roots of the ethno-medicinal plant Rubus ellipticus. Antioxidant activities were tested using DPPH, MCA and FRAP assays, whereas chemical profiling of fungal extract was illustrated by using gas chromatography and mass spectrometry (GC–MS) analysis. The ethyl acetate extract of C. parvula showed IC50, 47.75 ± 3.6 µg/mL for 2, 2-diphenyl-1-picryl-hydrazyl, 53.36 ± 2.6 µg/ mL for metal chelating assay and 360.54 ± 8.6 AAE/g dry extract for ferric reducing antioxidant power antioxidant activity assay. GC–MS analysis revealed the presence of octanal, 2-(phenylmethylene)- (16.24%), 1-(4-Iopropylphenyl)-2-methylpropyl acetate (12.91%), and benzoic acid, 2-hydroxy-, phenylmethyl ester (11.85%) as major compounds. Findings of the present study provide the basis for further research on individual compounds to assess their potential, especially in the pharmacology sector.
