摘要

本研究测定了马鞭草(Veratrum album L.)的精油成分及其抗菌和抗氧化特性。使用气相色谱和气相色谱-质谱分析了白藜芦醇干燥气生部分精油的化学成分。抗菌活性采用盘扩散法测定。检测了植物的总抗氧化状态(TAS)、总氧化状态(TOS)和 2.2-二苯基-1-苦基肼(DPPH)自由基清除能力。分析结果表明,白藜芦醇精油的主要成分为十六烷(39.5%)、肉豆蔻酸(十四烷酸)(22.8%)、庚烷(6.5%)、茴香醚(4.9%)和 1,8- 丁烯(4.8%)。研究结果表明,植物茎叶部分的甲醇提取物对病原微生物生长的抑制率不同(14±0.1 - 34±0.3毫米)。经计算,茎和叶甲醇提取物的 TAS 值分别为 3.75±0.07 和 3.91±0.01 mmol,而 TOS 值分别为 6.14±0.13 和 6.54±0.05 μmol。DPPH 自由基的清除活性随植物提取物浓度的增加而增加。

Antimicrobial, antioxidant and essential oil studies on Veratrum album L. (Melanthiaceae)
In this study, essential oil components of the Veratrum album L. and the antimicrobial and antioxidant properties of these components were determined. The chemical composition of the essential oils of dried aerial parts of V. album was analyzed using GC and GC-MS. Antimicrobial activity was determined with the disk diffusion method. Total antioxidant status (TAS), total oxidant status (TOS) and 2.2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging capacity were detected for the antioxidant activity of the plant. According to the analysis results, the major essential oil components of the V. album were determined as hexacosane (39.5%), myristic (tetradecanoic) acid (22.8%), heptane (6.5%), anethole (4.9%) and 1,8- cineole (4.8%). The findings showed that the methanol extracts of the stem and leaf parts of the plant inhibited the growth of pathogenic microorganisms at different rates (14±0.1 - 34±0.3 mm). The TAS values of methanol extracts of stem and leaf parts of V. album were calculated as 3.75±0.07 and 3.91±0.01 mmol, while TOS values were calculated as 6.14±0.13 and 6.54±0.05 μmol. The scavenging activity of the DPPH radical increased depending on increasing concentrations of the plant extract.
