•Dodonaea viscosa is an aromatic and medicinal plant.•Aqueous extracts of D. viscosa were influenced on composition of the essential oil of rosemary and major constituents.•Allelopathic activity of D. viscosa on rosemary was confirmed.
The essential oil of Rosmarinus officinalis L. is widely used as a folk medicine. In this study, the allelopathic activity of Dodonaea viscosa (aqueous, and acetone extracts 0, 30, 60 and 100%) on R. officinalis L. was investigated under laboratory conditions. The essential oil of air-dried samples was obtained by hydro distillation and was analyzed by gas chromatography (GC) and gas chromatography/mass spectrometry. The effect of the of D. viscosa on the chlorophyll content, photosynthetic rate, total phenols content, proline content, and chemical composition in rosemary was evaluated. A significant reduction of chlorophyll content and photosynthetic rate was observed. On the other hand, an increase was detected in the total phenols and proline content. Aqueous extract increased the 1,8-cineol content from 4.6% to 7.0%, the camphor content from 4.8% to 8.9% and the borneol content from 4.1% to 7.2%. As a result, allelopathic activity of D. viscosa on rosemary was confirmed.
