| description | Due to the various hazards of using synthetic chemical compounds in pharmaceutics, agriculture, and industry, scientists and researchers do their best to explore and assess new green natural compounds from natural resources with potent activity. The essential oil (EO) from the resin collected from <i>Araucaria heterophylla</i> Salisb. was extracted by the microwave technique and chemically characterized via GC-MS analysis. Furthermore, the extract EO was assessed for its antioxidant and phytotoxic activities. The EO has 33 compounds, mainly terpenes (98.23%), and the major compounds were <i>α</i>-pinene (62.57%), <i>β</i>-pinene (6.60%), germacrene D (5.88%), and <i>β</i>-caryophyllene (3.56%). The extracted EO showed substantial antioxidant activity, where it showed IC<sub>50</sub> values of 142.42 and 118.03 mg L<sup>−1</sup> for DPPH and ABTS, respectively. On the other hand, the EO revealed considerable phytotoxicity against the weed <i>Chenopodium murale</i>, where the EO showed IC<sub>50</sub> values of 304.0, 230.1, and 147.1 mg L<sup>−1</sup>, for seed germination, seedling shoot growth, and seedling root growth, respectively. Moreover, the EO showed the same pattern of allelopathic inhibition against the weed <i>Sonchus oleraceus</i>, where it showed IC<sub>50</sub> values of 295.7, 224.5, and 106.1 mg L<sup>−1</sup>, for seed germination, seedling shoot growth, and seedling root growth, respectively. The present study showed that the extraction technique affects the constituents of the EO, particularly the quantitative composition. The EO of <i>A. heterophylla</i> resin also revealed considerable antioxidant and phytotoxic activity against weeds. Therefore, it can be considered a promising natural resource that could be integrated into the weed management approach. However, further study is recommended for deep characterization of their authentic compounds and evaluation of their mode of action(s) on a wide spectrum of weeds. |
