Chemical constituents and antibacterial activity of Prosopisfarcta (Fabacea)‎ fruit from Iraq-Kurdistan region

الملخص EN

The chemical constituents of di chloro methane and hexane extracts of Prosopis Farcta (Fabacea family)were studied by gas chromatography, mass spectrometry.

Their relative concentrations were determined and both extracts contained 8 expected compounds.

There were 7 compounds found in hexane extract which are: 1- methyl pyrrole (8.08 %), alpha-ethyl aspartate (9.96 %), spiropentane propyl (13.75 %), ethyl oleate (43.43 %), 1-iodo-n-Nonyliodide (7.6 %), Borane-diethyl (decyloxy) (9.34 %), Sulfurous acid, 2-ethyl hexyl ester (7.84 %).

While one compound was found in dichloromethane extract namely: 3-O-methyl-d-glucose (100 %) was recorded as the principle constituents.

The antibacterial activities of dichloromethane and hexane extracts were measured against three pathogenic bacteria, which are Staphylococcus aureus, Escherichia coli and Streptococcus Pneumonia using diffusion method.

Significant dissimilarities in the antibacterial activity of plant extracts were noticed depending on the type of bacterial strain and the concentration of plant extracts.
