In this study, antioxidant and antibacterial activities of Prosopis farcta (Fabaceae) were investigated. The extracts were derived from seed and fruit pod parts by Ethanol, Methanol, Octanol and n-heptan solvents. High performance liquid chromatography analysis was used to measure antioxidant activities. Among the extracts, the seed Octanol extract (IC50=0.95 μg/ml) showed the best antioxidant activity. Antioxidant activities in various solvents showed different trends that may be as a result of differences in polarity and H-bonding ability of each solvent. The highest phenolic content of P. farcta was also obtained by the Octanol extraction in both seed and pod organs. Antibacterial properties of extracts were only recorded by methanol and ethanol extracts of the fruit pods which inhibited the growth of Staphylococcus and Escherichia coli. The results of the present work indicated that the selective extraction of Prosopis farcta by appropriate solvents could be very important to obtain bioactive fractions.
