摘要： The essential oil of Mentha canadensis aerial parts was obtained by hydrodistillation and analyzed by gas chromatography (GC) and gas chromaotography-mas spectrometry (GC-MS). A total of 36 components of the essential oil were identified. The major constituents in the essential oil of M. canadensis were menthol (28.8 %), alpha-pinene (16.4 %), menthone (12.7 %), alpha-terpineol (6.3 %) and limonene (5.5 %). Four active constituents (limonene, menthol, alpha-pinene and alpha-terpinol) were isolated from the essential oil of M. canadensis based on bioactivity-directed fractionation. The essential oil of M. canadensis aerial parts exhibited nematicidal activity against cereal cyst nematodes (Heterodera avenae) and root-knot nematodes (Meloidogyne incognita) with LC50 values of 385.7 mu g/ml and 139.0 mu g/ml, respectively. The isolated constituents, menthol and alpha-terpinol possessed nematicidal activity against H. avenae and M. incognita with LC50 values of 242.5 mu g/ml, 190.3 mu g/ml and 147.4 mu g/ml, 115.2 mu g/ml, respectively. The study indicated that the essential oil of M. canadensis aerial parts and its two major constituents, alpha-terpineol and menthol have a potential to be developed to a natural nematicides for the control of nematodes.
