seeds (MOS), recognized as a nutritionally valuable food, are rich in diverse bioactive compounds and widely utilized for disease prevention and adjunctive therapy. However, their in vitro chemical constituents and in vivo blood-absorbed/metabolized components remain underexplored. This study pioneered the application of UPLC-Q-Exactive Orbitrap-MS to characterize MOS-derived compounds in vitro and in vivo, concurrently elucidating major constituents' fragmentation pathways via mass spectrometry. In vitro, 81 chemical components of MOS were preliminarily characterized. 38 blood-borne components, comprising 11 prototypes and 27 metabolites, were identified in serum samples from MOS-treated rats. A validated LC-MS/MS method was developed to quantify the pharmacokinetics of key bioactive compounds (6-gingerol, vanillin, and eugenol) in rat plasma. These findings establish a theoretical foundation for clarifying MOS composition, evaluating its dietary applications, and guiding further exploration of its pharmacological potential.
种子（MOS）被认为是一种具有营养价值的食物，富含多种生物活性化合物，广泛用于疾病预防和辅助治疗。然而，它们的体外化学成分以及体内吸收/代谢的成分仍未得到充分研究。本研究率先应用超高效液相色谱-四极杆-静电场轨道阱质谱联用技术（UPLC-Q-Exactive Orbitrap-MS）对MOS衍生的化合物进行体外和体内表征，同时通过质谱阐明主要成分的裂解途径。在体外，初步表征了MOS的81种化学成分。在经MOS处理的大鼠血清样本中鉴定出38种血源成分，包括11种原型和27种代谢产物。开发了一种经过验证的液相色谱-串联质谱法（LC-MS/MS）来定量大鼠血浆中关键生物活性化合物（6-姜酚、香草醛和丁香酚）的药代动力学。这些发现为阐明MOS的组成、评估其膳食应用以及指导进一步探索其药理潜力奠定了理论基础。
