Study of Constituents and Antimicrobial Potential of Oilsfrom SomeMedicinal PlantsGrownin Sudan

Abstract

In this study the oils from five plants of medicinal attributes (Cassiasiama, Cordia Africana, Poliostiyma themigii ,Detarium microcarpumand Aristolochia bracteolate ) have been investigated by GC.MS and theantimicrobial activity has been screened. The GC-MS analysis of thetargetoilsrevealedthepresenceofboth9-octadecenoicacidmethylester and 9,12-octadecadienoic acid methyl ester as major constituents infourspecies(Cassiasiama,CordiaAfricana,Poliostiymathemigii,Detariummicrocarpum).However,Aristolochiabracteolateoilcontained9-octadecenoic acid methyl ester while 9,12-octadecadienoicacid methyl ester was absent in this sample.All thefive studied oilscontainedhexadecanoicacidmethylesterasoneofthemajorconstituents.Methylstearatehavebeendetectedinallstudiedoilsexcept Detarium microcarpum. All the target oils have been assessed fortheir antimicrobial activity and differentantimicrobial responses havebeenrecorded.
