Investigation of Constituents of Rumex acetosa Fixed Oil and Biological Activity of the Oil

Abstract

The fixed oil of Rumexacetosa was extracted by maceration. GC-MS analysis was conducted. Major constituents are : 9-octadecanoic acid methyl Ester (38.41%) , Ethyl oleate ( 21.16%) , Hexadecanoic 1,2,3-propane-triyl ester (6.41%) , 9,12-octadecanoic acid methyl ester (4.28%). The oil was assessed for antimicrobial potency via cup plate agar diffusion bioassay against a panel of bacterial isolates. The oil showed significant activity against Pseudomonas aeruginosaand good activity against Escherichia coli. However it was partially active against staphylococcusaureus and fungus candida albicans.
