Constituents and Antimicrobial Potency of Oils From Some Plant Species

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.
