Zusammenfassung: | The volatile oil obtained from the leaves of Hydrocotyle bonariensis Lam (Araliaceae) was analyzed by GC, Chiral-GC and GC-MS. It was identified 14 compounds and the monoterpene (+)-limonene (53.6%) and sesquiterpene γ-muurolene (10.5%) were the main components. The allelopathic effects of the oil were evaluated against two seeds, Lactuca sativa and Allium cepa. The results show that the oil exhibited inhibition effects in the germination and seedling growth of plants species relative to the control. |
