This study aims to analyze the chemical composition of the essential oils (EOs) obtained from stems and umbels of as well the assessment of their biological activity. EOs were extracted by hydrodistillation and analyzed by gas chromatography coupled to mass spectrometry (GC/MS). The antioxidant properties were determined by DPPH and ABTS assays. The phytotoxic potential was assessed against dicots weeds ( and ), monocots weeds () and the crop . The antifungal activity was evaluated against four target phytopathogenic fungal strains. High diversity of compounds was detected in Eos, varying among plant parts and consisting mainly of -pinene (24.47-28.56%), sabinene (16.2-18.6%), -phellandrene (6.3-11.7%) and -ocimene (5.28-7.85%). EOs exhibited remarkable antioxidant activity, as well as interesting variable antifungal activities depending on the dose and fungi strain. The herbicidal activity of EOs showed significant efficacy on the inhibition of germination and seedling growth of all tested herbs. These results suggest that the EOs of represent a valuable source of antioxidant, antifungal and phytotoxic metabolites and could be potential candidates for pest management, contributing to the promotion of sustainable agriculture.
本研究旨在分析从[植物名称]的茎和伞形花序中获得的精油（EOs）的化学成分，并评估其生物活性。通过水蒸馏法提取精油，并采用气相色谱-质谱联用（GC/MS）进行分析。通过DPPH和ABTS试验测定抗氧化性能。评估了对双子叶杂草（[杂草名称1]和[杂草名称2]）、单子叶杂草（[杂草名称3]）和作物[作物名称]的植物毒性潜力。针对四种目标植物病原真菌菌株评估了抗真菌活性。在[植物名称]的精油中检测到了高度多样的化合物，不同植物部位有所差异，主要成分包括α-蒎烯（24.47 - 28.56%）、桧烯（16.2 - 18.6%）、β-水芹烯（6.3 - 11.7%）和β-罗勒烯（5.28 - 7.85%）。[植物名称]的精油表现出显著的抗氧化活性，以及根据剂量和真菌菌株而变化的有趣的抗真菌活性。精油的除草活性对所有测试草本植物的发芽和幼苗生长抑制显示出显著效果。这些结果表明，[植物名称]的精油是抗氧化、抗真菌和植物毒性代谢物的宝贵来源，可能是害虫管理的潜在候选物，有助于促进可持续农业。
