Abstract: The volatile components of maple concrete were extracted by solvent extraction and qualitatively and quantitatively identified by gas chromatography-mass spectrometry. The results showed that 15 chemical constituents were identified in maple concrete, the main components of which were isobutyl phenylacetate （32.13%）, phenylacetic acid （28.53%）, methylcyclopentenolone （24.68%）,5-Hydroxymethylfurfural （7.04%）, methylcyclopentenolone is a characteristic ingredient of maple concrete, with a flavor similar to coffee and caramel. Methylcyclopentenolone, isobutyl phenylacetate, 5-hydroxymethylfurfural, DDMP, and the like constitute a caramel aroma unique to maple concrete.

Key words: maple concrete, volatile constituents, GC-MS
