In this study, chemical profiling of BCFW was performed using UHPLC-Q-Exactive Orbitrap MS in both full-scan and complementary modes. A chemical database of BCFW was constructed from 30 botanical ingredients, with compounds identified through diagnostic ions and fragmentation patterns and further verified using literature sources. Headspace gas chromatography-ion mobility spectrometry (HS-GC-IMS) was employed to profile volatile organic compounds (VOCs) in both BCFW and base wine, and chemometric analysis revealed batch-to-batch variations. A total of 658 compounds were identified, including 590 non-volatile and 68 volatile constituents. HS-GC-IMS fingerprints revealed generally consistent VOC profiles across batches, with notable differences observed in S1, S7, and S10. This comprehensive chemical characterization of BCFW provides a valuable reference for quality assessment and control.PMID:42006664 | PMC:PMC13091127 | DOI:10.1016/j.fochx.2026.103819
