Abstract

The chemical composition, and phytotoxic and antifungal activities of the essential oils isolated by using hydrodistillation from the aerial parts of Tunisian rue were evaluated. Significant variations were observed among harvest periods. The analysis of the chemical composition by gas chromatography/mass spectrometry showed that 2-undecanone (33.4-49.8%), 2-heptanol acetate (13.5-15.4%) and α-pinene (9.8-11.9%) were the main components. The antifungal ability of rue essential oils was tested by using disc agar diffusion against ten plant pathogenic fungi. A high antifungal activity was observed for the essential oil isolated at flowering developmental phase. Furthermore, rue essential oils showed high level of herbicidal activity against several weeds.

摘要

对采用水蒸馏法从突尼斯芸香地上部分分离得到的挥发油的化学成分、植物毒性和抗真菌活性进行了评估。在不同采收期观察到显著差异。通过气相色谱/质谱联用仪对化学成分进行分析表明，2-十一酮（33.4-49.8%）、乙酸2-庚酯（13.5-15.4%）和α-蒎烯（9.8-11.9%）是主要成分。采用滤纸片琼脂扩散法对芸香挥发油对十种植物病原真菌的抗真菌能力进行了测试。在开花发育期分离得到的挥发油具有较高的抗真菌活性。此外，芸香挥发油对几种杂草表现出较高水平的除草活性。
