ANTIOXIDANT AND ANTIMICROBIAL ACTIVITIES OF ENDEMICTREE ABIES NUMIDICA GROWING IN BABOR MOUNTAINS FROM ALGERIA

The aim of present study was to determine the antimicrobial and antioxidant activity of essential oil and different extracts from Abies numidica leaves. The 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay was used to detect in vitro antioxidant activity. Antibacterial activity was tested against nine bacterial species, representing both Gram positive and Gram negative bacteria. Antifungal activity was evaluated using two Candida species. The results indicate that the crude methanolic extracts and the essential oil resulted in the highest antioxidant activities compared to other solvents. All extracts of A. numidica showed antimicrobial activity against both Gram positive and Gram negative bacteria, as well as fungi, especially methanolic extracts and essential oil. A. numidica could be exploited for the isolation of bioactive compounds which could be a potential source for antioxidant and antimicrobial activities.
