Traditionally, (Korean mint) has been widely used to treat various infectious diseases. The aims of this study were to: (i) determine the phenylpropanoid content of the plant using high-performance liquid chromatography; (ii) undertake total anthocyanin, flavonoid, and phenolic assays; (iii) and evaluate the antioxidant and antibacterial properties of the methanol extracts from the stem, leaves, and flowers of Korean mint. The total anthocyanin, flavonoid, and phenolic content assays showed that the flowers had higher phenolic levels than the stem and leaves. The reducing power, the 2,2-diphenyl-1-picrylhydrazyl superoxide radical scavenging abilities, and the hydrogen peroxide radical scavenging activities were also evaluated so that the antioxidant activities of the extracts from the different plant parts could be evaluated. The flower extracts revealed higher antioxidant properties than the other parts. The antibacterial properties of the methanol extracts from . were analyzed by the disc diffusion method, and the flower extracts had higher antibacterial activities against the six bacterial strains used in the study than the other parts. This study provides information on the synergistic antioxidant and antibacterial properties of phenolics derived from the different parts of Korean mint.
传统上，（薄荷）已被广泛用于治疗各种传染病。本研究的目的是：（i）使用高效液相色谱法测定该植物的苯丙素含量；（ii）进行总花青素、黄酮类化合物和酚类物质的测定；（iii）评估薄荷茎、叶和花的甲醇提取物的抗氧化和抗菌性能。总花青素、黄酮类化合物和酚类物质含量测定表明，花中的酚类水平高于茎和叶。还评估了还原能力、2,2-二苯基-1-苦基肼超氧自由基清除能力和过氧化氢自由基清除活性，以便评估不同植物部位提取物的抗氧化活性。花提取物显示出比其他部位更高的抗氧化性能。通过纸片扩散法分析了薄荷甲醇提取物的抗菌性能，花提取物对研究中使用的六种细菌菌株的抗菌活性高于其他部位。本研究提供了有关薄荷不同部位酚类物质协同抗氧化和抗菌性能的信息。
