Evaluation of biological activity and chemical content of some medicinal plants using different methods

الملخص EN

This study was conducted to evaluate the biological and chemical effectiveness of some medicinal plants using different methods.

Five species of medicinal plants(Origanum majorana, Lawsonia inermis, Salvia officinolis, Conocarpus erectuus and Zizphus spina-christi)were used as antimicrobial for three types of bacteria (Staphylococcus aureus, Proteus mirabilis and Pseudomonas aeruginosa) and antioxidants agents.

The study included the use of four organic solvents (ethanol, methanol, acetone) and water for the purpose of determining the efficiency of each solvent in the separation of active compounds.

Secondary metabolism compounds, were detected by qualitative detection.

Antioxidants were tested by the 2,2-diphenyl-1-picrylhydrazyl(DPPH) test and total phenolic content(TPC) was calculated.

Antibiotics (Amikacin, Gentamicin, Imipenem, Norflaxacin, Tetracycline, Tobramycin, Trimethoprim, Vancomycin) were used.

Imipenem antibiotic was better than all plant extracts
