The use of species' plant extracts and essential oils, which are rich in bioactive compounds (allelochemicals), could support weed management. This study focused on the chemical analysis and evaluation of the allelopathic potential of plant extracts (PEs) and essential oils (EOs) of and on the germination and early seedling growth of weeds ( and ) . The plant extract from showed higher antioxidant activity (IC = 0.171 ± 0.01 mg/mL) and phenolic content than that from (IC = 0.263 ± 0.01 mg/mL). Chlorogenic acid was the most abundant phenol in both extracts. However, contained a higher amount (1.694 ± 0.081 mg/g) and exhibited a stronger inhibitory effect on the germination of (EC = 0.54 ± 0.02%) and (EC = 1.51 ± 0.07%) compared to . The dominant components of essential oil were β-thujone (18.9%), cis-ocimene epoxide (7.88%), and bicyclogermacrene (7.04%), while the main constituents of essential oil included gurjunene (10.41%), cis-crysanthenyl acetate (7.17%), and γ-humulene (6.67%). The lowest EC values for essential oil regarding seed germination and seedling length were estimated for (0.28 ± 0.48% and 0.03 ± 0.00%, respectively), whereas was the most sensitive to essential oil (0.11 ± 0.04% and 0.02 ± 0.00%, respectively). All tested extracts showed allelopathic potential; however, the results indicate that the essential oils had a stronger inhibitory effect than the plant extracts.
使用富含生物活性化合物（化感物质）的植物提取物和精油可有助于杂草管理。本研究聚焦于[植物名称1]和[植物名称2]的植物提取物（PEs）和精油（EOs）的化感潜力的化学分析及其对杂草[杂草名称1]和[杂草名称2]萌发及幼苗早期生长的影响。[植物名称1]的植物提取物比[植物名称2]的植物提取物表现出更高的抗氧化活性（IC₅₀ = 0.171 ± 0.01 mg/mL）和酚类含量（IC₅₀ = 0.263 ± 0.01 mg/mL）。绿原酸是两种提取物中含量最高的酚类物质。然而，[植物名称1]的提取物含量更高（1.694 ± 0.081 mg/g），并且与[植物名称2]相比，对[杂草名称1]（EC₅₀ = 0.54 ± 0.02%）和[杂草名称2]（EC₅₀ = 1.51 ± 0.07%）的萌发表现出更强的抑制作用。[植物名称1]精油的主要成分是β-侧柏酮（18.9%）、顺式氧化罗勒烯（7.88%）和双环大根香叶烯（7.04%），而[植物名称2]精油的主要成分包括古芸烯（10.41%）、顺式菊烯乙酸酯（7.17%）和γ-葎草烯（6.67%）。[植物名称1]精油对[杂草名称1]种子萌发和幼苗长度的最低EC₅₀值分别为0.28 ± 0.48%和0.03 ± 0.00%，而[杂草名称2]对[植物名称2]精油最为敏感（分别为0.11 ± 0.04%和0.02 ± 0.00%）。所有测试的提取物均显示出化感潜力；然而，结果表明精油的抑制作用比植物提取物更强。
