Abstract

This study examined the phytochemical diversity, antioxidant capacity, and genetic relationships among species collected from western and central Iran. Significant interspecific and regional variation was observed in total phenolic and flavonoid contents, with from Khuzestan showing the highest phenolic (50.26 mg GAE/g DW) and antioxidant activity (DPPH: 70.40%, FRAP: 6.91 µmol Fe²/g DW). and also exhibited notable flavonoid and anthocyanin levels, respectively. Codeine content peaked in , while papaverine was highest in . Antioxidant traits correlated strongly with phenolic content and environmental variables such as humidity and elevation. PCA revealed clustering of antioxidant traits, while alkaloids and anthocyanins formed distinct patterns. Phylogenetic analysis indicated complex evolutionary relationships and possible introgression among species. These findings highlight substantial phytochemical and genetic variation shaped by local environments. As this study focuses on Iranian populations, broader geographic sampling is needed to generalize the patterns observed.

摘要

本研究调查了从伊朗西部和中部采集的物种的植物化学多样性、抗氧化能力及亲缘关系。总酚和黄酮含量存在显著的种间和区域差异，胡齐斯坦省的样本酚含量最高（50.26毫克没食子酸当量/克干重），抗氧化活性也最高（DPPH：70.40%，FRAP：6.91微摩尔Fe²/克干重）。另外，[物种名称1]和[物种名称2]分别表现出显著的黄酮和花青素水平。可待因含量在[物种名称3]中最高，而罂粟碱在[物种名称4]中含量最高。抗氧化特性与酚含量以及湿度和海拔等环境变量密切相关。主成分分析揭示了抗氧化特性的聚类，而生物碱和花青素形成了不同的模式。系统发育分析表明物种间存在复杂的进化关系和可能的基因渗入。这些发现凸显了受当地环境影响的大量植物化学和遗传变异。由于本研究聚焦于伊朗种群，需要更广泛的地理采样以推广所观察到的模式。
