Métabolites secondaires bioactifs des champignons endophytes isolés de Retama raetam (Forssk.).

Abstract

This study was conducted to evaluate the antimicrobial, antioxidant and enzymatic activity of endophytic fungi isolated from Retama raetam Forssk., a plant of the Fabaceae family collected in Bordj Bou Arréridj region Algeria). Ethyl acetate and chloroform extracts obtained from six fungi had positive antimicrobial activity results when tested against 12 pathogenic bacteria, one yeast as well as two phytopatogenic fungi using the disc diffusion method. Inhibition zones vary between 0 and 25 mm for the ethyl acetate extracts, and from 0 and 19 mm for the chloroform extracts. The antioxidant activity of the crude ethyl acetate extracts was also tested. 83% of endophytes extracts have antioxidantactivity. For the enzymatic activity, 16.66% of fungi have esterase, 50% have protease, 50% have lipase and 33.33% have an amylase.
