A Study on Antibacterial Activities of Aloe Vera Leaves, Stems and Roots on some Selected Organisms
Subscribe/Renew Journal
This study is provoked by the paucity of information on the antibacterial or pharmacological activities of Aloe vera stems and ischolar_mains. The antibacterial activity of Aloe vera leaf, stem and ischolar_main extracts on three organisms (Pseudomonas aeruginosa, Salmonella typhi and Proteus mirabilis) was investigated using agar well diffusion method. The Aloe vera leaf extract proved to be most effective. Both Aloe vera leaf Cold Water Extract (CWE) and Ethanol Crude Extract (ECE) demonstrated significant antibacterial activity against the sampled organisms. CWE of Aloe vera stem showed no antibacterial activity in the bacterial species while ECE had antibacterial activity on Pseudomonas aeruginosa and Proteus mirabilis. The ischolar_main CWE and ECE only exhibited antibacterial activity on Proteus mirabilis. The stems had no antibacterial activity on Salmonella typhi and Pseudomonas aeruginosa. The extract with the highest antibacterial properties was ECE of Aloe vera ischolar_mains. There is therefore a need for the inclusion of Aloe vera ischolar_mains in Aloe vera antibacterial efficacy studies.
