In contrario the seed extract of T. foenum-graecum had no antioxidant activity while Aspergillus sp. 2, isolated from the seeds, showed significant TAC [(18.0 ± 0.1) mg/mL These results indicated that no correlation between the TACs of the endophytes and the host plants can be established. The main factor is the fungal genus, indeed Aspergillus spp. were recorded the highest TAC.
