Analysis of Phytochemical Constituents and Antimicrobial Activities of Aloe vera L. Against Clinical Pathogens
نویسنده
چکیده
The aim of the study was to investigate the Aloe vera phyto chemical compounds and antimicrobial activity of different extracts. The phytochemical compound screened by qualitative and GC-MS method. Qualitatively analyzed Tannin, Saponin, Flavonoids and Terpenoids gave positive results and phlobactanins and Steriods and Steriods gave negative results. In the GC-MS analysis, 26 bioactive phytechemical compounds were identified in the ethanolic extract of Aloe vera. Three different solvents such as aqueous, ethanol and acetone were used to extract the bioactive compounds from the leaves of Aloe vera to screen the antimicrobial activity selected human clinical pathogens by agar diffusion method. The maximum antibacterial activities were observed in acetone extracts (12±0.45nm, 20±0.35nm, 20±0.57nm and 15±0.38nm) other then aqueous extracts and ethanol extract. Antifungal activity of Aloe vera was analyzed gains Aspergillus flavus and Aspergillus niger. The maximum antifungal activity was observed in acetone extracts (15±0.73nm and 8±0.37nm) when compared other extracts. Aloe vera plant extract with acetone can be used as antimicrobial agents.
