Abstract:
In this study the oils from five plants of medicinal attributes (Croton cordofana, Cissus quadrangularis, Syzygium aromaticum ,Croton zambesicus and Hibiscus sabdariffa) have been investigated by GC-MS and the antimicrobial activity has been screened. Gas chromatography - mass spectrometry has been used for the identification and quantification of the constituents of Syzgium aromaticum oil. The analysis revealed the presence of 13 components dominated by: eugenol (60.35%). GC-MS analysis of Croton zambesicus oil revealed the presence of 22 components dominated by :9-octadecenoic acid methyl ester(12.98%). Hibiscus sabdarifa oil gave 24 constituents. Major component being :9-octadecenoic acid (Z)-, methyl ester (30.23%). Cissus quadrangularis oil was studied by GC-MS. The analysis showed the presence of 37 constituents dominated by:E,E,Z-1,3,12-nonadecatriene-5,14-diol(22.11%). Croton cordofana oil revealed the presence of 19 components. Major component is: 9 , 12-octadecadienoic acid methyl ester (44.32% ).The target oils have been assessed for their antimicrobial potency and different antimicrobial responses has been observed.
