A Novel Approach for Rapid Screening of Stilbenes in Plant Extracts Based on SALDI Mass Spectrometry

Key Points

• This research aims to develop a new variation of SALDI mass spectrometry for identifying stilbenes in plant extracts.
• Utilized SALDI mass spectrometry to obtain tandem mass spectra of stilbenes.
• Analyzed complex samples to determine component composition directly in plant tissues.
• Assessed spatial distribution of secondary metabolites in plants.
• High-quality tandem mass spectra were acquired for stilbenes.
• The approach enabled direct analysis of plant tissues.
• Enhanced understanding of the spatial distribution of secondary metabolites was achieved.
