Abstract:
Five plants of medicinal attributes have been investigated. The oils of these plants have been extracted by maceration and then characterized by GC-MS. In addition the antimicrobial activity of the targeted oils has been assessed. GC-MS analysis of Hyphane thebaica oil was performed and fifty constituents have been detected. GC-MS analysis of Acacia mellifera oil showed that the fatty acids accounts for (87.40%) of the bulk of the oil. Parkinsonia aculeata oil gave 33 constituents dominated by : 9,12- octadecadienoic acid methyl ester (40.51%) and hexdecanoic acid methyl ester (16.89%) . Lucaena leucocephala oil gave 30 constituents .Major components are: 9,12-octadecadienoic acid-z,z- methyl ester (37.29%) and hexadecanoic acid methyl ester (18.17%). Sorghum bicolor oil has been analyzed by GC-MS. Thirty three components were detected .The oil has been dominated by : 9,12-octadecadienoic acid (35.91%) and pentadecanoic acid (11.46%).
The studied oils have been evaluated for their antimicrobial activity and different antimicrobial responses have been observed.
