AI Article Synopsis
- - The study analyzes the chemical makeup and antibacterial effects of essential oil extracted from Eugenia platysema leaves, identifying 22 compounds using techniques like GC-FID and GC-MS.
- - The major component discovered was phytol, a diterpene, constituting 66.05% of the oil, marking its first identification in Eugenia species, with elixene as the second most common at 9.16%.
- - Antibacterial testing revealed that the essential oil showed no activity against various bacteria strains at concentrations up to 1000 μg/mL.
Article Abstract
This study describes the qualitative and quantitative chemical composition and evaluates the antibacterial activity of essential oil from Eugenia platysema leaves. Analysis by GC-FID and GC-MS allowed the identification of 22 compounds. Different from the other species of the Eugenia genus, the major compound found in the essential oil was the diterpene phytol (66.05%), being this the first report of the presence of this compound in the essential oils from Eugenia genus. The sesquiterpene elixene was the second most concentrated compound in the studied essential oil (9.16%). The essential oil from E. platysema was tested for its antibacterial activity against cell-walled bacteria and mollicute strains of clinical interest using the microdilution broth assay. The results showed that the essential oil of E. platysema was inactive until 1000 μg mL(-1) against tested bacteria.
