• To identify key metabolites and pathways involved in fruit maturation.

Main Methods:

• Widely targeted metabolomics using multiple reaction monitoring.
• Analysis of metabolites across three distinct fruit developmental stages.
• Hierarchical cluster analysis and metabolic pathway enrichment analysis.

Main Results:

• Identified 655 metabolites across all developmental stages.
• Revealed six distinct metabolite expression patterns.
• Discovered 69 up-regulated differential metabolites in mature fruits.
• Found significant enrichment in flavonoid and phenylalanine/tyrosine/tryptophan biosynthesis pathways.

Conclusions:

• Metabolic profiling provides insights into banana fruit development.
• Identified key pathways offer targets for functional compound isolation.
• Findings support enhanced utilization of banana resources.
