Chemical Composition and Allelopathic Effect of Essential Oil of Litsea pungens

Natural plant resources with herbicidal activity may be substitutes for synthetic chemical pesticides, likewise aromatic extracts, especially essential oils. Essential oil from Litsea pungens has been proved to possess a strong antibacterial property. Interestingly, we found the also showed allelopathic capacity. Therefore, in present work, composition of fruit L. was analyzed by gas chromatography–mass spectrometry (GC–MS). The weed control abilities were further evaluated. results show that yield extracted steam distillation 1.4%, and 17 compounds, mainly terpenoids, identified GC–MS. In tests, exhibited negative effect on seed germination rate seedling growth Lolium perenne Bidenspilosa. Moreover, chlorophyll content, malondialdehyde electrolyte leakage, catalase, superoxide dismutase peroxidase seedlings treated negatively affected. This work could provide better understanding rational utilization crop cultivation development environment-friendly herbicides.
