Abstract
In this study, the growth inhibiion  potential of methanol, ethanol, acetone, and chloroform extracts of rind, gel, latex and whole leaf of Aloe vera was evaluated using agar diffusion disc method. The bacteriostatic and bactericidal activity were also tested by minimal inhibitive and bactericidal concentration methods. Results showed that all leaf parts of A. vera had antibacterial potential. Methanol could release more growth inhibitory substances than other solvents studied in disc diffusion method. Results also showed that chloroform released the lowest amount of bacteriostatic and bactericidal substances. Leaf gel showed more bacteriostatic and bactericidal activities than other leaf parts of the plant. In total, 31 chemicals were identified using gas chromatography, of which 25 were found in latex. Some antibacterial substances such as cinnamic acid, tetradecanoid acid, 2-hydroxy propionate, sitosterol, carvone, lupeol, 1-heptanol, 2-propyle, 1, 2-banzan di-carboxylic acid were found in different parts of A. vera leaf. Based on the overall results, the antibacterial activity of A. vera against the pathogenic bacteria can be considered as a biocontrol potential in the future.
