GC-MS Analysis and Antimicrobial Activity of Oils From Some Medicinal Plants

Abstract

In this research five plants used in Sudanese system of medicine have been investigated. The oils of the targeted species have been extracted by maceration and the constituents of the oils have been characterized by GC-MS. Furthermore the antimicrobial potential of the oils has been evaluated. GC-MS analysis of Acacia nubica oil gave 24 components dominated by: 9,12-octadecanoic acid methyl ester (31.54%) and 9-octadecanoic acid methyl ester (15.86%). The oil of Foeniculum vulgare was investigated by GC-MS. The analysis revealed 53 components. The oil contained fatty acids (87.83%) .Cordia Africana oil gave 27 components dominated by 9,12-octadecadienoic acid (Z,Z)-, methyl ester (37.02%) and hexadecanoic acid, methyl ester (18.02%).GC-MS analysis of Lens culaniris oil gave 26 constituents dominated by 9,12-octadecadienoic acid methyl ester (37.49%) and hexadecanoic acid methyl ester (20.28%). Analysis Acacia polycantha oil showed 32 constituents . Major components are : 9,12-octadecadienoic acid methyl ester(27.95%) and methyl stearate(17.13%).The oils have been evaluated for their antimicrobial activity and different antimicrobial responses have been detected.
