ethanolic extract (ORE) was prepared via ultrasonication-assisted ethanolic extraction and enriched through silica gel and macroporous adsorption resin chromatography to afford a non-/weakly polar fraction (ORE-S) and a polar fraction (ORE-N), respectively. This study aimed to (1) quantify major bioactive components (e.g., polyphenols, alkaloids, and terpenes) in ORE-S and ORE-N, (2) assess their antioxidant activities, (3) correlate compositional differences with antioxidant function, and (4) identify key antioxidant compounds along with their potential mechanisms of action. By integrating widely targeted metabolomics with network pharmacology, we not only elucidated how enrichment methods influence the antioxidant properties of ORE but also demonstrated the potential of ORE-N as a valuable source of bioactive compounds and natural antioxidants.
乙醇提取物(ORE)通过超声辅助乙醇提取法制备,并分别通过硅胶和大孔吸附树脂色谱法进行富集,得到一个非/弱极性组分(ORE-S)和一个极性组分(ORE-N)。本研究旨在:(1)定量测定ORE-S和ORE-N中的主要生物活性成分(如多酚、生物碱和萜类);(2)评估它们的抗氧化活性;(3)将成分差异与抗氧化功能相关联;(4)鉴定关键抗氧化化合物及其潜在作用机制。通过将广泛靶向代谢组学与网络药理学相结合,我们不仅阐明了富集方法如何影响ORE的抗氧化特性,还证明了ORE-N作为生物活性化合物和天然抗氧化剂宝贵来源的潜力。
