The lack of systematic comparative analyses on their active compounds and underlying biosynthetic mechanisms has limited the application and development of\n                    <jats:italic>A. stolonifera<\/jats:italic>\n                    . To address this gap, we conducted integrated metabolomic and transcriptomic analyses of leaves from both species. Using GC-MS for targeted profiling of volatile organic compounds and UPLC-ESI (-Q TRA)-MS\/MS for flavonoids and lignin pathway intermediates, we identified 1,728 differentially accumulated metabolites (DAMs). Transcriptome sequencing generated 37.61 Gb of clean data, revealing 18,000 differentially expressed genes (DEGs). Kyoto Encyclopedia of Genes and Genomes analysis demonstrated significant divergence in terpenoid and flavonoid biosynthesis pathways between the two species.\n                    <jats:italic>A. stolonifera<\/jats:italic>\n                    exhibited accumulation sesquiterpenoids, consistent with the concerted upregulation of mevalonate pathway genes (e.g.,\n                    <jats:italic>AACT1-4<\/jats:italic>\n                    ,\n                    <jats:italic>HMGR1-3<\/jats:italic>\n                    ) and sesquiterpene synthases (\n                    <jats:italic>BAS1<\/jats:italic>\n                    ,\n                    <jats:italic>LUP2<\/jats:italic>\n                    ,\n                    <jats:italic>CAMS1<\/jats:italic>\n                    ,\n                    <jats:italic>XF1<\/jats:italic>\n                    ). Conversely,\n                    <jats:italic>A. argyi<\/jats:italic>\n                    exhibited enrichment of monoterpenoids and flavonoids, associated with elevated expression of methylerythritol phosphate pathway genes (\n                    <jats:italic>DXS2<\/jats:italic>\n                    ,\n                    <jats:italic>DXR1-5<\/jats:italic>\n                    ), monoterpenoid biosynthesis genes (\n                    <jats:italic>SDR2-4<\/jats:italic>\n                    ,\n                    <jats:italic>TPS14<\/jats:italic>\n                    ), and flavonoid biosynthesis genes (e.g.,\n                    <jats:italic>CHS1-2<\/jats:italic>\n                    ,\n                    <jats:italic>CHI<\/jats:italic>\n                    ,\n                    <jats:italic>F3H1-3<\/jats:italic>\n                    ).
