The chemical composition of aloe vera peel / Nurul Izzati Mohamed

Aloe vera is one of the plant that gave many benefits to human health. Aloe vera peel is a part of Aloe vera which has chemical composition and biological activities such as antimicrobial, antioxidant, anticancer and anti-inflammatory. The ethanol and hexane extracts of Aloe vera peel was characterized and analyzed by using GC-MS and FTIR. Different conditions and solvents (ethanol and hexane) were used to analyze the chemical composition of Aloe vera peel. Compounds that were found in both conditions in ethanol extract of Aloe vera were consists of 1,2 Benzenedicarboxylic acid, phytol, and Dodecyl cis-9, 10-epoxyoctadeconoate. In hexane extract, phytol remains as the major chemical composition that acts as antimicrobial, anticancer and anti-inflammatory. The best condition for the extraction of Aloe vera peel is at room temperature compared to heat at 60°C at 60 minutes due to high temperature might damage the biological activities of chemical composition. The FTIR analysis shows that the functional compounds in the Aloe vera peel were aromatic acid halide, aliphatic acid halide, ester, carboxylic acid and methyl -CH3. The basic study is focused to determine the chemical compounds from Aloe vera peel using Gas Chromatography - Mass Spectrometry (GCMS) and to differentiate the compounds present from Aloe vera peel at different conditions and solvents.
