Abstract

Aloe yemenica, which is widely distributed in Yemen, is a species belonging to the plant genus Aloe (family :Aloaceae). To the best of our knowledge, there is lack of Information on the antibacterial effect of this species and hence this study was undertaken. The main objective of this study was to assess the potential antibacterial activity of aloe yemenica against pseudomonas aeruginosa which is one of the most virulent bacteria that causes serious diseases in human. Three test samples of the plant were prepared including the fresh gel of the leaf (inner leaf), powder of the dried gel and liquid extracts. The latter were prepared by either hot or cold extraction methods using either distilled water, ethanol 96 % or chloroform as extracting solvents. Results of this study showed that only the aqueous extract prepared by hot extraction has a considerable in vitro antipseudomonal activity.
