Despite the harsh conditions and limited water resources of the Arabian Peninsula, plants that live in this environment contain a variety of bioactive compounds and have been used in traditional medicines for thousands of years. We investigated the effects of ethanol extracts of Tamarix arabica and Salvadora persica on Gram-negative and Gram-positive bacteria. The investigations were include; the inhibition of the bacterial growth, determination of MIC and MBC, detection of kill-time, potassium and phosphorus leakages and detection of the bioactive compounds by the GC-MS analysis. The tested extracts in combination, at a 1:1 volume ratio, showed high inhibitory effects, as reflected by the minimum inhibitory concentrations and minimum bactericidal concentrations. The new EC plate was used to determined MBC and kill-time. Further, the detection of phosphate and potassium leakage indicated a loss of selective permeability of the cytoplasmic membrane after treatment with these extracts. The bioactive compounds in the ethanol extracts of T. arabica and S. persica may offer a less expensive and natural alternative to pharmaceuticals.
