In this study, the whole plant of Euphorbia hirta. L was investigated for phytochemical and antifungal properties. Hydroethanolic extract of E. hirta has been fractioned with different organic solvents and were analysed for chemical screening, antioxidant and antifungal activities against Fusarium moniliforme and Phoma sorghina. The results showed that E. hirta L contains tannins, flavonoids, alkaloids and terpenoids. Ethyl acetate and butanol fractions of E. hirta L present high contents of phenolic compounds with respectively 3.675 and 3.588 mg gallic acid equivalent per gram of extract. The antioxidant activities evaluated by FRAP showed that these two fractions contain 4.147 mg and 3.977 mg Trolox equivalent per gram of extract, respectively. The antifungal activity investigated on Fusarium moniliforme and Phoma sorghina shows that 5 mg/ml of these extracts inhibit the mycelium growth of these fungi at 58.33% and 44.67% respectively and demonstrate that these extracts could be used for cereals protection.
