英文摘要
For this research, 50 kinds of commonly used essential oils were analyzed to investigate their DPPH (1, 1-dipheny1-2-picrylhydrazyl) free-radical scavenging ability, trolox equivalent antioxidant capacity, total phenolic contents, and chemical composition. Of all theessential oils studied, the DPPH free-radical scavenging ability, trolox equivalent antioxidant capacity, and total phenolic content of clove essential oil proved to be the best. A quantity of 10 mg/mL of clove essential oil displayed a 94.08% DPPH free radical scavenging ability, and its EC50 was 87 μg/mL. Additionally, it had the highest trolox equivalent antioxidant capaciyt (78.89 mmol of trolox/g) and totalphenolic content (4887 μg/g). GC-MS analysis determined a eugenol quantity of 87.32% in clove essential oil. These results reveal that the DPPH free-radical scavenging ability and trolox equivalent antioxidant capacity of clove essential oil
exhibit a positive correlation with the total phenolic content.
