摘要: 采用超高效液相色谱-串联质谱(UPLC-MS/MS)和电感耦合等离子体质谱(ICP-MS)技术,系统分析南柴胡(BS)与北柴胡(BC)种子的代谢组学特征及无机元素组成。通过非靶向代谢组学共鉴定出4282种代谢物,其中脂类及类脂分子(33.60%)、有机酸及其衍生物(15.50%)和有机杂环化合物(15.30%)为主要成分。多变量统计分析显示两组代谢谱存在显著差异(累计贡献率91.04%),共筛选出2960个差异代谢物(DAMs),其中苯丙素类与聚酮类化合物在BC组特异性上调(VIP≥1,P<0.05)。元素分析表明,K和Ca含量在两组中均最高,BS组的Na、Al、Mo、B含量明显高于BC组。所有样品重金属含量均符合2025年版《中华人民共和国药典》标准。相关性分析表明,BS组以Na-Al共变和Fe-Cr协同为特征,而BC组则表现为Na-Ca关联及Fe与Ni、Bi、Re的拮抗关系。研究首次揭示了南、北柴胡种子在代谢物和元素积累上的种间特异性差异,为柴胡种质资源评价提供了代谢-元素双维度指标,其发现对指导品种选育和规范化种植具有重要价值。

Abstract: This study employed ultra-performance liquid chromatography–tandem mass spectrometry (UPLC- MS/MS) and inductively coupled plasma mass spectrometry (ICP-MS) to systematically characterize the metabolomic profiles and inorganic elemental composition of seeds from Bupleurum scorzonerifolium (BS) and B. chinense (BC). Using untargeted metabolomics, a total of 4282 metabolites were identified, dominated by lipids and lipid-like molecules (33.60%), organic acids and derivatives (15.50%), and organoheterocyclic compounds (15.30%). Multivariate statistical analyses revealed pronounced differences between the two metabolomic datasets (cumulative explained variance: 91.04%), and 2960 differential accumulated metabolites (DAMs) were screened, with phenylpropanoids and polyketides specifically upregulated in the BC group (VIP≥1, P<0.05). The contents of K and Ca are the highest in both groups, while Na, Al, Mo, and B levels were significantly higher in the BS group than in the BC group. The concentrations of heavy metals in all samples complied with the limits specified in Chinese Pharmacopoeia (2025 edition). Correlation analysis showed that the BS group was characterized by Na–Al co-variation and Fe–Cr synergy, whereas the BC group exhibited Na–Ca associations and antagonistic relationships between Fe and Ni, Bi, and Re. This study is the first to reveal interspecific differences in metabolites and element accumulation in seeds of southern Bupleurum and northern Bupleurum, providing dual-dimension (metabolite–element) indicators for the evaluation of Bupleurum germplasm resources. These findings have important implications for guiding cultivar breeding and promoting standardized cultivation.
